Summary: As global plastic consumption continues to rise, the accumulated plastic in the natural environment poses a threat to human survival. Photoreforming, a simple and low-energy method, can convert wasted plastic into fuel and small organic chemicals at room temperature. In this study, a noble-metal-free, non-toxic, and easily prepared mesoporous ZnIn2S4 photocatalyst was used to photoreform polylactic acid (PLA), polyethylene terephthalate (PET), and polyurethane (PU), producing small organic chemicals and H-2 fuel under simulated sunlight. The mesoporous ZnIn2S4 exhibited high efficiency in H-2 production, strong redox ability, and long-term photostability. Moreover, it could overcome the hindrances of dyes and additives in realistic wasted plastic bags and bottles, achieving high decomposition efficiency and providing an efficient and sustainable strategy for plastic upcycling.

Summary: By controlling the volume of ionic liquid used in synthesis, the heteroatom doping and morphology of CoNi metal-organic frameworks (MOFs) are modulated to generate CoSe2-NiSe2 heterojunction structures wrapped by N, P, F tri-doped carbon (NPFC) after a selenisation process. The unique cubic porous structure of CoSe2-NiSe2/NPFC exhibits a five times higher specific surface area than the sheet-like hollow structure produced without ionic liquid. The formation of heterojunctions and doping of heteroatoms successfully lower the Delta G(H*) and Delta G(OH*) values, leading to excellent activity for HER in both acidic and alkaline solutions and outstanding performance in a flexible solid-state supercapacitor.

Summary: Iron-nitrogen moieties encapsulated in N-doped graphitic and hierarchical biochars were derived from hydrothermal pyrolysis and microwave NH3 activation of cellulose and lignin, with cellulose-derived biochars showing superior activities in oxygen reduction reaction (ORR) compared to lignin-derived biochars. Among them, the C-1% biochar exhibited the best electrocatalytic performance and followed a near four-electron ORR route, attributed to the active iron-nitrogen sites covered with hierarchical carbon shells. The incorporation of iron-nitrogen in cellulose-derived biochars through a time-saving and energy-efficient microwave activation procedure may have potential applications in ORR.

Summary: This study demonstrates the growth of CsPbBr3 nanoparticles on semiconducting graphene oxide and conductive few-layer graphene surfaces, showing different interfacial charge transfer behaviors. The rate constant of charge transfer can be modulated by controlling the composition ratio of graphene oxide and few-layer graphene. The relationship between CO2 to CH4 conversion rate and charge transfer rate differs between the graphene oxide-based and few-layer graphene-based nanoheterostructures. This work provides important insights for the design of perovskite-graphene based nanoheterostructures with remarkable performance for solar-driven CO2 conversion.
