“…The hierarchical Cu 2 O/rGO favours deeper oxidation and the formation of FA (Figure 6c), consistent with more oxidizing equivalents potentially resulting from longer charge carrier lifetimes, and faster charge transfer kinetics (vide infra). [47] Furthermore, Cu 2 O/rGO exhibited excellent photostability over five consecutive reactions ( Figure S8).…”

Hierarchical Cu2O nanospheres with a Pompon Dahlia‐like morphology were prepared by a one‐pot synthesis employing electrostatic self‐assembly. Nanocomposite analogues were also prepared in the presence of reduced graphene oxide (rGO). Photophysical properties of the hierarchical Cu2O nanospheres and Cu2O/rGO nanocomposite were determined, and their photocatalytic applications evaluated for photocatalytic 4‐chlorophenol (4‐CP) degradation and H2 production. Introduction of trace (<1 wt %) rGO improves the apparent quantum efficiency (AQE) at 475 nm of hierarchical Cu2O for H2 production from 2.23 % to 3.35 %, giving an increase of evolution rate from 234 μmol.g−1.h−1 to 352 μmol.g−1.h−1 respectively. The AQE for 4‐CP degradation also increases from 52 % to 59 %, with the removal efficiency reaching 95 % of 10 ppm 4‐CP within 1 h. Superior performance of the hierarchical Cu2O/rGO nanocomposite is attributable to increased visible light absorption, reflected in a greater photocurrent density. Excellent catalyst photostability for >6 h continuous reaction is observed.

“…However, in the present work, the uniform flower-like microspherical morphology of BiVO 4 and BiVO 4 /Bi 2 Ti 2 O 7 was prepared without addition of any surfactants. As well-known that the absence of surfactants, the geometrical or individual building components of a material may be regarded as a route for the formation of flower-like morphology by a self-assembly process [30][31][32][33].…”

“…Recently, there are many valuable reports of graphene‐based composite materials like rGO/TiO 2, rGO/SnO 2 and rGO/BiVO 4. Wang et al used different ratios of rGO/BiVO 4 for the photo‐degradation of rhodamine B under visible light (λ > 400 nm). Wang et al employed rGO/BiVO 4 in the same way for the degradation of methylene blue.…”

A novel heterogeneous composite material based on reduced graphene oxide (rGO) and bismuth vanadate (BiVO4) was prepared and characterized by various techniques such as powder XRD, HRTEM, EADX, UV–Vis‐DRS, FT‐IR, Raman, BET and XPS analyses. The characterization results reveal that the rGO well decorated by BiVO4. The electrochemical impedance spectroscopy (EIS) shows the increasing of charge transfer of rGO/BiVO4 in presence of light irradiation. In this research, the pure BiVO4 and rGO/BiVO4 composite have been explored for photocatalytic reduction of nitroarenes. Among the prepared nanocomposites, rGO loaded with 10% BiVO4 catalyst (noted as rGO/BiVO4–10%) shows the best performance for the photo‐reduction of various nitroaromatic molecules to their corresponding amine compounds under visible‐light irradiation at room temperature. The catalyst exhibited in particular excellent photocatalytic activity for the conversion of 1,4‐dinitrobenzene to 4‐nitroanilline (100% conversion) in 20 min, 4‐chloronitrobenzene to 4‐chloroaniline and 2‐nitrophenol to 2‐aminophenol (100% conversion) in only 30 min. In addition, the conversion of 4‐bromonitrobenzene, 4‐iodonitrobenzene to their corresponding amine compounds (100% conversion) was achieved in 60 min. The catalyst was recovered for several times and reused without decreasing of its efficiency.
