An increasing interest in utilizing biomass resources to develop bioplastics, aiming to mitigate the environmental and energy issues resulting from the use of petroleum-based plastics. However, bioplastics that suffering from poor interface bonding and hydrophilicity of the feedstock usually exhibit inadequate mechanical properties, water stability and functionality, which hinder their practical applications. Herein, a simple and effective strategy was proposed to develop high-performance starch-based bioplastics with thermoplastic by 2,2,6,6-tetramethylpiperidine 1-oxy-oxidized cellulose nanofibers and different modified starch fillers coupled with chemical cross-linking reinforcement. Due to the full utilization of the advantages of each component, outstanding interface bonding and rich chemical cross-linking, all the obtained modified starch-based bioplastics demonstrated excellent mechanical properties (up to 20.52 MPa) and superior water stability. Besides, the starch-based bioplastics could be reused after dissolution-regeneration, and completely biodegradable after disposal. At the same time, the starch-based bioplastics exhibited remarkable heat-sealing properties, which provided more convenient possibility of producing packaging materials for bioplastics used in different fields.

Hydrogel electrolytes with high intrinsic toughness and ionic conductivity are considered essential for realising flexible energy storage. Polyzwitterionic hydrogel electrolytes typically exhibit excellent ionic transference number and conductivity because of their distinct rapid anionic and cationic channels, thereby achieving superior ionic transport kinetics. This paper presents an ultrafast autocatalytic gelation process, which can produce a self-adhesive hydrogel electrolyte (PAD@SC) via copolymerization of vinyl monomer acrylic acid and zwitterionic monomer sulfobetaine in a time scale of seconds instead of hours at room temperature (approximately 20 ℃). The incorporation of bio-based functional enhancement components, namely, sodium lignosulfonate and nanocellulose, into the hydrogel precursor solution facilitated the reconstruction of noncovalent hydrogen bond networks within the hydrogel, resulting in enhanced mechanical properties. Moreover, the PAD@SC hydrogel electrolyte prepared using this autocatalytic system can effectively inhibit the growth of Zn dendrites to realize a stable Zn anode. The assembled PAD@SC-based flexible Zn-ion capacitors possess high specific capacitance (85.4 mAh g-1), rate performance, and cycling stability (10000 cycles at 5 A g-1), indicating remarkable potential for practical application in flexible power supplies. © 2023, The Authors.

Solar-driven semiconductor photocatalysis water splitting is considered a green and efficient method for hydrogen production. But the severe recombination of photogenerated carriers limits the efficiency of hydrogen production. The introduction of transition metal co-catalyst can form an internal electric field (IEF) with semiconductor to achieve efficient directional transfer of photogenerated electron-holes. However, the aggregation of transition metal co-catalyst and the formation of metal-hydrogen bonds are still the main problems for limiting hydrogen production efficiency. Here, metal-organic framework (MOF) derived porous carbon encapsulated transition metal Fe (Fe@C) and ZnInS are loaded on carbonized cellulose fibers (CCF) to construct composite paper for photocatalytic water splitting into hydrogen. The MOF-derived carbon skeleton can provide high conductivity and disperse Fe co-catalyst for increasing the active sites. Moreover, the encapsulation of Fe in the 3D carbon skeleton can avoid the formation of metal-hydrogen bonds and improve the hydrogen adsorption and desorption capacity. The CCF as a carrier is beneficial to improve the dispersibility and reusability of Fe@C and ZnInS. The hydrogen evolution rate of the composite paper is as high as 63.8 mmol h g under visible light irradiation. After 5 photocatalytic cycles, the hydrogen evolution rate remains at 94.2 % and the loading state of Fe@C and ZnInS on CCF is maintained. This work provides a new idea for fabrication of high-efficient photocatalytic paper, and develops the application potential of MOF derivatives in photocatalysis.

Triazine intumescent flame retardant (IFR) PP composites have been widely used in electronic appliances, rail transit, and aerospace fields due to their low smoke, high efficiency and environmental friendliness. However, with the increasing attention to safe production and sustainable development, the green and safe synthesis and biomaterialization of traditional triazine char-forming agents have received extensive attention. Herein, a bio-based triazine char-forming agent N-propionyltriazine-ethylenediamine copolymer (PTEC) was successfully prepared by bio-based β-alanine and cyanuric chloride as raw materials under a pure water system for the first time. A novel bio-based IFR (BIFR) system was constructed with ammonium polyphosphate. Only 24 wt% BIFR make PP pass the UL-94 V-0 rating, and the LOI of PP/BIFR was improved to 29.7 %. Compared to pure PP, the smoke and heat release rate of PP/BIFR composites were decreased by 54.5 % and 76.2 %, respectively. The introduction of BIFR promoted the dehydration and charring of PP composites, and released many inert gases during pyrolysis, which led to the rapid expansion of composites. The formed dense and high-strength char layer exerted excellent shielding effect in the condensed phase. In addition, the PP/BIFR composites retained excellent mechanical properties, and the flexural strength and ductility were significantly improved with the addition of BIFR. This study provided a new way for the safe production and biomaterialization of triazine char-forming agents, and the prepared bio-based PP composites with excellent flame retardancy and mechanical properties showed a great application prospect in construction, building materials and other emerging fields. © 2025 Elsevier Ltd

High-filled wood-plastic composite (HFWPC) is a new type of composite with great environmental and economic benefits because it contains significant biomass contents and minimizes the use of plastics. However, the defects of poor mechanical properties, high water absorption, poor drying-wetting cycle resistance, which greatly limits its long-term use in a high-humidity environment. In this study, an in-situ microfibrillated polyethylene terephthalate (PET)/high-density polyethylene (HDPE) polyblend was prepared using an extrusion hot stretching process, and was used as the shell of the co-extruded high-filled wood-plastic composite (Co-HFWPC). Co-HFWPC exhibited excellent mechanical properties and water stability. The flexural strength and tensile strength increase by 114% and 97%, The Co-HFWPC has an extremely low water absorption (less than 0.6%) and its mechanical property retention rate was more than 90% after 20 drying-wetting cycles, and the creep strain of the Co-HFWPC decreased with increasing PET content in the shell layers. This study provides insight into an efficient and low-cost method for large-scale preparation of high-strength, water-resistance and creep-resistance Co-HFWPC and extended their application areas like constructing materials and some extreme circumstances. © 2023, The Authors.

Developing high-performance catalysts is a crucial area of research for efficiently utilizing light energy. In this study, a lamellar spherical structure of Cu2(OH)2CO3 was utilized to synthesize Cercis chinensis clustered CuO/g-C3N4 heterojunctions. These heterojunctions were then further improved through in situ orogenesis initiated by the steam and CO2 produced during the decomposition of Cu2(OH)2CO3. This strategy avoided the dilemma of multi-step synthesis of traditional heterojunctions, and further overcome the trouble of removing templates. The heterojunction results in a significant increase in CH4 production in the photocatalytic CO2 reduction reaction. The rate increases to 18.61 μmol·g-1·h-1, which is 4.68 times higher than that of pure g-C3N4 and 16.32 times higher than that of CuO. Moreover, the heterojunction effective exciton separation, mass transfer, and distinct morphology result in a CH4 selectivity of over 75%. In comparison, pure g-C3N4 exhibits a CH4 selectivity of 52%, while CuO demonstrates a selectivity of 36.3%. This work provides a potential and simple strategy for the in situ construction of novel photocatalysts with heterojunctions and special morphologies. © 2023, The Authors. All rights reserved.

Photo-Fenton reaction has received increasing attention in the removal of antibiotic pollutants in water. Herein, Fe 2 O 3 -on-ZrO 2 octapods, Fe 2 O 3 with rod-shaped cone precisely aligned on each lattice plane of ZrO 2 octahedron, were designed and synthesized via simple reflux heating and baking, combined lattice plane recognition with heteroepitaxial directional growth strategies. There are a large number of Fe 2 O 3 -on-ZrO 2 heterojunctions closely connected by Fe-O-Zr bond, which conduce to the separation and transmission between photoinduced e - and h + , accelerate the iron cycle and then generate more highly active free radicals to promote the decomposition of tetracycline hydrochloride (TC-HCl). Fe 2 O 3 -on-ZrO 2 had high adsorption energy for H 2 O 2 by DFT calculation, which greatly speeded the participation of H 2 O 2 . The results of photo-Fenton degradation experiments showed that under UV-vis light irradiation, more than 95% TC-HCl solution was degraded by Fe 2 O 3 -on-ZrO 2 in 25 minutes within full pH range, which demonstrated excellent photo-Fenton performance and the pH limit broken. Finally, the possible degradation path and reasonable degradation mechanism were speculated by HPLC-MS, SKP, ESR etc. This work exhibited a new structure and degradation mechanism, which would further encourage researchers to study the rational regulation of materials with special morphology and structure. © 2022, The Authors.

The biodiesel prepared from Xanthoceras Sorbiflia Bunge Oil catalyzed by Ce doped nano PO_4^(3-)/ZrO_2 was investigated. A maximum biodiesel yield of 91.83% was achieved at the concentration of Ce^(3+) up to 0.1 mol/L, calcination temperature 500 °C, calcination time 3.0 h, and the concentration of phosphoric acid of 3.5 mol/L. Ce-nano PO_4^(3-)/ZrO_2 catalyst activities were correlated with the observed physico-chemical characteristics derived from scanning electron microscopy(SEM), FT-infrared(FT-IR), X-ray diffraction(XRD), thermogravimetric(TG) and Brunauer-Emmett-Teller(BET) analysis. The delayed crystallization of ZrO_2 made surface oxides have more defects which were beneficial to the adsorption of PO_4^(3-) by the concentration increment of Ce^(3+). The chemical composition of synthesized biodiesel was confirmed by gas chromatography(GC). The characteristics of Xanthoceras Sorbiflia Bunge oil were found within the optimal range in accordance with Chinese No. 0 diesel standard as a substitute diesel fuel.
