Transition metal chalcogenides have nowadays garnered burgeoning interest owing to their fascinating electronic and catalytic properties, thus possessing great implications for energy conversion and storage applications. In this regard, their controllable synthesis in a large scale at low cost has readily become a focus of research. Herein we report diatomite-template generic and scalable production of VS_2 and other transition metal sulfides targeting emerging energy conversion and storage applications. The conformal growth of VS_2 over diatomite template would endow them with defect-abundant features. Throughout detailed experimental investigation in combination with theoretical simulation, we reveal that the enriched active sites/sulfur vacancies of thus-derived VS_2 architectures would pose positive impacts on the catalytic performance such in electrocatalytic hydrogen evolution reactions. We further show that the favorable electrical conductivity and highly exposed sites of VS_2 hold promise for serving as sulfur host in the realm of Li-S batteries. Our work offers new insights into the templated and customized synthesis of defect-rich sulfides in a scalable fashion to benefit multifunctional energy applications.

This paper focuses on multi-agent systems with uncertain disturbances, in which only the bounding functions on the disturbances and the bounds on the initial state of each agent are known. By designing a neighborhood interval observer for this kind of multi-agent system, the estimation of the sum of the relative state of each agent associated with itself and its neighbors is frstly realized. Then, on the basis of these estimated information, local control algorithm is designed to drive the system to achieve bounded consensus.

Peptide hydrogels have been widely used for diverse biomedical applications. However, our current understanding of the physical principles underlying the self-assembly process is still limited. In this review, we summarize our current understanding on the physical chemistry principles from the basic interactions that drive the self-assembly process to the energy landscapes that dictate the thermodynamics and kinetics of the process. We discuss the effect of different factors that affect the kinetics of the self-assembly of peptide fibrils and how this is related to the macroscopic gelation process. We provide our understanding on the molecular origin of the complex and rugged energy landscape for the self-assembly of peptide hydrogels. The hierarchical self-assembled structures and the diverse self-assembling mechanism make it difficult and challenging to rationally design the physical and chemical properties of peptide hydrogels at the molecular revel. We also give our personal perspective to the potential future directions in this field.

The treatment of sewage sludge is an increasing environmental and social concern due to its daily generation in large quantities. In this study, sewage sludge was pyrolyzed at adjusted temperatures to produce biochar (SBC300, SBC500, SBC700 and SBC900) for the rational regulation of surface Fe species as a catalyst for peracetic acid (PAA)-based water decontamination. The highest bisphenol A removal (99.9 % in 10 min, k obs = 0.602 min −1 ) was achieved by SBC900, and both adsorption and degradation were enhanced due to increased surface area and electron-rich functional groups (especially C O), and the Fe(III) to Fe(II) transformation and defects (I D /I G = 0.96), respectively. The Fe(II)/ Fe(III) redox dominated PAA activation, and lattice oxygen and PAA induced inherent/generated Fe(III) to Fe(II). Alkoxy radicals (R-O , mainly CH 3 C(O)O and CH 3 C(O)OO ), OH and O 2 − were produced but only R-O and OH were reactive species, suggesting a complete radical pathway. This study offers an economic and handy scheme for the efficient reuse of waste-derived catalysts and provides atomic-level activation mechanisms.

The three different morphologies BiPO nanocrystals（rods, spindles and spindle-like assembled nanosheets） were successfully synthesized by hydrothermal method. The as-prepared products were characterized using X-ray diffraction analysis, infrared analysis, scanning electron microscopy analysis and ultraviolet-visible diffuse reflectance analysis. XRD results show that BiPO samples presented monoclinic phase monazite structure, hexagonal phase + monoclinic phase and hexagonal phase + monoclinic phase monazite structure. The results showed that the BiPO has superior photocatalytic activity with the addition of SDS,and IPA, SO and BQ have been used to capture ·OH, h+ and ·O, respectively. Capture of ·OH and h+ in BiPO crystals clearly showed that ·OH and h+ played a major role in the photocatalytic proc

In this paper, Ni（NO）·6HO was used as the nickel source, Fe（NO）3·9 HO as the iron source, thiourea as the sulfur source by hydrothermal method（the amount of thiourea was changed respectively to be 0.1 g, 0.15 g, 0.2 g, 0.25 g） to compound Fe-Ni alloy materials, and the composite products were loaded onto carbon cloth. It was found that when the amount of thiourea was 0.15 g, the composite has the best hydrogen evolution performance.

In the past decades, numerous efforts have been devoted to improving the catalytic activity of nanocomposites by either exposing more active sites or regulating the interaction between the support and nanoparticles while keeping the structure of the active sites unchanged. Here, we report the fabrication of a Co 3 O 4 −CeO 2 nanocomposite via overturning the loading direction, i.e., loading an inert CeO 2 support onto active Co 3 O 4 nanoparticles. The resultant catalyst exhibits unexpectedly higher activity and stability in peroxymonosulfate-based Fenton-like reactions than its analog prepared by the traditional impregnation method. Abundant oxygen vacancies (O v with a Co⋅⋅⋅O v ⋅⋅⋅Ce structure instead of Co⋅⋅⋅O v ) are generated as new active sites to facilitate the cleavage of the peroxide bond to produce SO 4 .− and accelerate the rate-limiting step, i.e., the desorption of SO 4 .− , affording improved activity. This strategy is a new direction for boosting the catalytic activity of nanocomposite catalysts in various scenarios, including environmental remediation and energy applications.

Serious safety risks caused by the high reactivity of lithium metal against electrolytes severely hamper the practicability of lithium metal batteries. By introducing unique polymerization site and more fluoride substitution, we built an in situ formed polymer-rich solid electrolyte interphase upon lithium anode to improve battery safety. The fluorine-rich and hydrogen-free polymer exhibits high thermal stability, which effectively reduces the continuous exothermic reaction between electrolyte and anode/cathode. As a result, the critical temperature for thermal safety of 1.0 Ah lithium-LiNi 0.5 Co 0.2 Mn 0.3 O 2 pouch cell can be increased from 143.2 °C to 174.2 °C. The more dangerous “ignition” point of lithium metal batteries, the starting temperature of battery thermal runaway, has been dramatically raised from 240.0 °C to 338.0 °C. This work affords novel strategies upon electrolyte design, aiming to pave the way for high-energy-density and thermally safe lithium metal batteries.
