Summary: The report describes the preparation of Bi2Se3/rGO composites through a hydrothermal method. SEM and Raman spectra were used to analyze the microstructures and morphology properties of the composites, indicating a well-prepared and high crystalline material. PEC tests showed that the Bi2Se3/rGO heterojunction exhibited enhanced photocatalytic performance compared to pure Bi2Se3, with rGO facilitating efficient separation of electron-hole pairs.

Summary: In this study, we used first-principles calculations to theoretically investigate the electronic properties of monolayer GaSe1-xTex alloys. Substituting Se with Te resulted in changes in the geometric structure, charge distribution, and bandgap. These changes were attributed to complex orbital hybridizations. This study highlights the strong dependence of energy bands, spatial charge density, and projected density of states (PDOS) on the concentration of substituted Te.

Summary: Mimicking natural processes like plant photosynthesis requires a deep understanding of molecular building blocks. Bulk photocatalytic materials used in artificial photosynthesis limit CO2 conversion efficiency and yield. However, nanostructured photocatalysts offer hope for improved efficiencies. CO2 conversion to solar fuels and value-added chemicals is a significant scientific advance. Fabrication of novel nanostructured photocatalysts is crucial for CO2 reduction.

Summary: Utilizing carbon nanomaterials, such as carbon nanotubes and graphene, to develop resilient and strong multifunctional composites has been a common theme in nanomaterials research. However, the dream of creating super-strong materials based on carbon nanomaterials has not yet been realized. This paper systematically reviews the strength, fracture, and failure mechanisms of carbon nanotubes, carbon nanofibers, and graphene. The limitations and inevitable defects in these materials are discussed, as well as the potential for developing super-tough structural materials by combining different dimensional carbon nanomaterials.
