The overall energy efficiency (EE) is critical for commercializing promising electrochemical technologies, such as the carbon dioxide reduction reaction (CO2RR). Despite the rapid development of advanced catalysts and reactors for CO2RR, its commercial potential is still hindered by the sluggish oxygen evolution reaction (OER), which causes high cell voltages and low EEs. Herein, we developed a NiOOH@Ni3S2 catalyst on the surface of nickel foam (NF) via an electrochemical surface reconstruction strategy. We observed that the oxidation of glycerol (GLY) to formate (FA) is more thermodynamically favorable than the OER on the developed NiOOH@Ni3S2/NF catalysts. The Ni2+/Ni3+ redox couples within the NiOOH@Ni3S2 heterojunction enhance the charge transfer kinetics between the active sites and adsorbed reaction intermediates, facilitating the highly selective and active generation of FA from GLY oxidation reaction (GOR), with a remarkable Faradaic efficiency (FE) of 94% achieved at 100 mA·cm−2. Comprehensive mechanistic studies identified that the reaction pathway towards FA generation starts from glyceraldehyde intermediates, and glycolate was considered as the key species. Moreover, benefiting from the efficient conversion of CO2 to FA on bismuth nanosheets, the GOR//CO2RR paired electrolysis system realizes a remarkable overall FE of ca. 190% for FA co-production at 160 mA·cm−2 (cathodic FE: 91.25% and anodic FE: 98.70%). This proceeds at a cell voltage of ca. 2.32 V, which is ca. 0.85 V lower than that of OER-assisted CO2RR system at the same current density. This work provides new insights for co-upgrading CO2 and biomass to value-added chemicals. © The Author(s) 2025.

To obtain a lightweight and high-strength wood sandwich structure, a wooden lattice sandwich cell element was designed in combination with a pyramid-type structure. After inserting glue to prepare the cell unit, the influence of panel thickness and core diameter on the unit cell force was analyzed and compared under the condition of flat pressure. Under the condition of flat pressure, the specific strength of the unit cell was higher than that of the specific strength of the composition material, and the unit cell may be regarded as a structure with high specific strength. Theoretical predictions, simulation analysis, and experimental tests demonstrated that the structure compressive capacity depended on the diameter of the core when the core length was set. The larger the diameter of the core is, the stronger the bearing capacity of the unit cell will be. When the diameter of the core is constant, the longer the core length is, the weaker the bearing capacity of the unit cell will be. The simulation analysis was in agreement with the experimental test results, indicating that the destruction of the structure was mainly caused by the failure of the core. © 2018, bioResources.

An efficient solar water evaporator is an important strategy for addressing the problem of water shortage. Constructing high-performance solar interfacial evaporators through bionic design has become a crucial approach for performance enhancement. Through the study of zebra patterns, it has been found that the black-and-white alternating patterns generate vortices on the surface of the zebra's skin, thereby reducing the temperature. By utilizing the vortices brought about by the temperature difference, the design of a solar water evaporator is created based on the bionic zebra pattern, so as to improve its water evaporation performance. In this work, green and sustainable wood is used as the base of the evaporator, and the bionic design of zebra stripes is adopted. Meanwhile, the following research is conducted: The wood is cut into thin slices with dimensions of 30 × 30 × 5 mm, and a delignification treatment is performed. Tannic acid-Fe ions are used as the photothermal material for functionalization. A series of stable patterned water evaporators based on delignification wood loaded with tannic acid-Fe ion complex (TA-Fe) are successfully prepared. Among them, the wood-based solar water evaporator with 3 mm zebra stripes exhibits excellent photothermal water evaporation performance, achieving a water evaporation rate of 1.44 kg·m·h under the illumination intensity of one sun. Its water evaporation performance is significantly superior to that of other coating patterns, proving that the bionic design of zebra patterns is effective and can improve water evaporation efficiency. This work provides new insights into the development of safe and environmentally friendly solar interfacial water evaporation materials through bionic design.

This paper demonstrates the additive manufacture of swimming micro-robots which combine a hydrophobic nanofibrillated cellulose aerogel with a low acoustic impedance porous piezoelectric ceramic to provide long-term buoyancy and improved propulsion. The hydrophobic nanocellulose aerogel is shown to exhibit a high and stable contact angle that was maintained for extended periods of time, which facilitates long-term and stable buoyancy of the micro-robot. To quantify the benefits of introducing porosity into the active piezoelectric element, a new analysis model was developed to inform material design and maximize the propulsion force. Detailed characterisation and modelling of the swimming robots demonstrated that a swimming robot based on a lead-free porous Ba0.85Ca0.15Zr0.1Ti0.9O3 (BCZT) ceramic exhibited a higher acoustic radiation propulsion force and faster swimming speed compared to a robot fabricated using a dense ceramic element. These benefits were associated with the lower elastic modulus, density and acoustic impedance of the porous material. The lower permittivity, reduced device capacitance, and lower resonant frequency of the porous piezoelectric element also significantly reduced the driving current and power requirements of the robot. This work therefore provides new insights on the impact of acoustically matched piezoelectric materials on the performance of swimming micro-robots and successfully demonstrates the use of porosity to improve acoustic impedance matching of resonant piezoelectric devices, such as micro-robots and ultrasonic transducers. © 2024, The Authors.

Angewandte Chemie 2023年第32期135卷

Lignin solubilization and in situ hydrogenolysis are crucial for reductive catalytic fractionation (RCF) of lignocellulose to aromatic monomers. In this study, we reported a typical hydrogen bond acceptor of choline chloride (ChCl) to tailor the hydrogen-donating environment of the Ru/C-catalyzed hydrogen-transfer RCF of lignocellulose. The ChCl-tailored hydrogen-transfer RCF of lignocellulose was conducted under mild temperature and low-pressure (<1 bar) conditions, which was applicable to other lignocellulosic biomass sources. We obtained an approximate theoretical yield of propylphenol monomer of 59.2 wt % and selectivity of 97.3 % using an optimal content of ChCl (10 wt %) in ethylene glycol at 190 °C for 8 h. When the content of ChCl in ethylene glycol was increased to 110 wt %, the selectivity of propylphenol switched toward propylenephenol (yield of 36.2 wt % and selectivity of 87.6 %). The findings in this work provide valuable information for transforming lignin from lignocellulose into value-added products.

Coating performance on glutaraldehyde-modified wood

Journal of Forestry Research 2019年第1期30卷 353-361页

Scots pine(Pinus sylvestris L.) panels were modified with glutaraldehyde(GA) to various weight percent gains and subsequently coated with several commercial coatings. The drying rate and adhesion of the coatings on the modified wood were measured; the coated/modified woods were exposed outdoors to analyze how the wood modifications influence the coating deterioration. The results showed that GA modification caused an increase in the drying rate of the waterborne coatings, but had no influence on drying of tested solvent-borne coatings. GAmodification did not change the dry adhesion but reduced the wood strength in a pull-off test. Wet adhesion of waterborne coatings was improved, while that of the solvent-borne coatings tended to be somewhat reduced. During 22 months of outdoor weathering, the coated/modified samples exhibited lower moisture content than the coated/unmodified samples, but GA modification didn't contribute a substantially synergistic effect with surface coatings on resistance to weathering.

The objective of this paper is to improve the interfacial bonding between the oxidized bamboo fiber and epoxy resin by grafting amino-functionalized multi-walled carbon nanotubes. Bamboo fiber was oxidized by a 2,2,6,6-Tetramethylpiperidine-1-oxyl oxidation system. The amino-functionalized multi-walled carbon nanotubes were then grafted on its surface by impregnation method. It was found by single fiber pull-out testing that the interfacial bonding between the bamboo fiber and epoxy resin was improved by 31.5% after the oxidation treatment of the fiber. After further grafting 0.5wt% amino-functionalized multi-walled carbon nanotubes, the interfacial bonding was improved by 106.4%. The fracture morphologies and AFM scanning results of individual sample revealed the mechanism of the treatment from amino-functionalized multi-walled carbon nanotubes strengthens interfacial bonding between the fiber and epoxy. The effect of the amino-functionalized multi-walled carbon nanotubes content on the interfacial properties of the bamboo fiber/epoxy resin was investigated, a threshold for the content was identified. © 2022, The Authors.

Cobalt-catalyzed transfer hydrogenation of nitroarenes to arylhydroxylamines with NH 3 BH 3 : Scope and mechanism

引用

Journal of Catalysis 2025年 449卷

作者： Dawei Gong Yanlin Zhang Qixuan Li Yufei Li Linan Xing Lina Zhao Degong Kong Key Laboratory of Preparation and Application of Environmental Friendly Materials Ministry of Education College of Chemistry Jilin Normal University Changchun 130103 PR China Department of Chemistry Southern University of Science and Technology Shenzhen 518000 PR China Key Laboratory of Bio-Based Material Science and Technology Ministry of Education College of Material Science and Engineering Northeast Forestry University Harbin 150040 PR China

A novel cobalt-catalyzed transfer hydrogenation of nitroarenes to arylhydroxylamines using ammonia borane (NH 3 BH 3 ) in methanol has been developed. The cobalt catalyst exhibits good selectivity without producing over-reduced by-products. Density functional theory (DFT) calculations and control experiments provide valuable insights into the reaction mechanism, revealing the N–H moiety of NH 3 BH 3 as a key participant in nitroarene reduction. Moreover, DFT calculations reveal that selective control is achieved via the unique square-pyramidal coordination of the cobalt complex with NH 3 BH 3 and hydroxylamine. This coordination ensures that the reduction of nitrobenzene halts at the hydroxylamine stage, enabling the selective reduction of nitrobenzene to hydroxylamine. Moreover, methanol is indirectly involved in the reaction and does not provide hydrogen atoms directly for nitroarene reduction, which differs from the classical solvent-mediated protonolysis mechanism. This study presents a novel and straightforward method for synthesizing arylhydroxylamines.
