Summary: This study synthesized a novel heterostructured photocatalyst by coupling indium hydroxide with nitrogen-doped graphene aerogels. The photocatalyst showed impressive photodegradation performance for the model pollutant p-NP, mainly attributed to the synergistic effects between indium hydroxide and graphene aerogels. The efficient photocatalytic degradation was achieved through the favorable formation of photo-generated holes and hydroxyl radicals. Comparative evaluation with another indium-based heterostructured material demonstrated the superior performance of the synthesized photocatalyst.

Summary: In this study, hierarchical ZnO nanosheet-reduced graphene oxide (RGO) nanocomposites were prepared via a simple one-step process, with graphene oxide (GO) precursors effectively modulating the structure of ZnO nanosheets. By controlling the weight ratio of GO, the shape of the ZnO nanosheets could be tuned. The ZnO-RGO composites showed good photocatalytic performance for ethylene oxidation under simulated sunlight, with the optimal mass ratio of GO enhancing the stability and mineralization rate of ethylene to nearly 100%. The enhanced photo-oxidation performance was attributed to the intimate contact between RGO nanosheets and ZnO nanoparticles, promoting light absorption intensity and charge carrier separation.

Summary: In this study, a bifunctional catalyst was developed for simultaneous dephosphorylation and 4-nitrophenol (4-NP) reduction. The catalyst was obtained by in-situ growth of NiFe layered double hydroxide on reduced graphene oxide/polyelectrolytes assembly nanolayers. The results showed that the catalyst could activate dephosphorylation of para-nitrophenyl phosphate (p-NPP) at 20 degrees C and the catalytic efficiency increased with temperature. Furthermore, the by-product 4-NP formed through dephosphorylation was fully converted to 4-aminophenol by the catalyst within 15 minutes.

Summary: A direct low-cost chemical reduction method is presented for the synthesis of the ternary Cu-Cu2O-CuO system, where the presence of graphene oxide helps limit the conversion of copper to copper oxide. The composition of the ternary system can be altered by adjusting the amount of copper precursor used, as confirmed by X-ray diffraction studies and XPS analysis of the synthesized nanocomposites. The enhanced catalytic efficiency of the composite nanostructures towards visible light photodegradation and hydride reduction reactions is attributed to the interaction between graphene sheets and copper, as well as the unique ternary composition of Cu2O-Cu-CuO.

Summary: Two composites, 0.5Y2O3/Al2O3-Cu/30Mo3SiC and 0.3GO-0.5Y2O3/Al2O3-Cu/30Mo3SiC, were fabricated by fast hot press sintering. The effects of doped reduced graphene oxide (rGO) on the hot deformation behavior and microstructure of 0.5Y2O3/Al2O3-Cu/30Mo3SiC composites were investigated. The presence of molybdenum carbide (MoC) layers/nanoparticles at the rGO-Cu/Mo interface improved the interfacial bonding of the composite. Additionally, the addition of rGO resulted in enhanced flow stress and activation energy of hot deformation.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.
