Summary: CeO2@ZnO nanocomposites were prepared by pyrolyzing Ce@Zn metal-organic frameworks, which showed improved photocatalytic performance due to the formation of a nanoheterojunction structure. The effects of the Zn:Ce ratio on the microstructure, morphology, and optical properties of the nanocomposites were studied. The prepared photocatalysts exhibited higher photocatalytic activity than previously reported CeO2@ZnO nanocomposites, suggesting their potential in environmental remediation.

Summary: By controlling the dosage of triethanolamine, two nanocomposites of monoclinic-ZrO2@rGO and tetragonal-ZrO2@rGO were successfully prepared, with the tetragonal-ZrO2@rGO exhibiting a higher adsorptive amount for OTC. Both nanocomposites show a selective uptake of OTC among tetracycline antibiotics, with adsorption reaching equilibrium in 15 minutes and being independent of pH in the range of 4-8. The interactions between OTC and the nanocomposites were revealed through Fourier transform infrared and XRD analysis, with surface complexation, pi-pi, and cation-pi bonding interactions playing a crucial role.

Summary: A facile one-pot synthesis method was used to prepare CeVO4/BiVO4/rGO nanocomposites, followed by investigation of their photocatalytic performance for dye degradation. Loading CeVO4/BiVO4 nanoparticles onto reduced graphene oxide (rGO) significantly enhanced the photocatalytic efficiency, attributed to increased surface area and improved charge separation.

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: The occurrence of pharmaceutical pollutants in the environment is a growing concern and effective strategies for their elimination are needed. Photocatalysis has been recommended as an efficient approach, and in this study, a boron-oxide-decorated nitrogen-rich reduced graphene oxide (B2O3/N-rGO) nanocomposite is synthesized and characterized for its photocatalytic performance toward ciprofloxacin (CIP) degradation. The results show that the B2O3/N-rGO nanocomposite demonstrates significantly enhanced photocatalytic activity compared to N-rGO and pure B2O3, making it a promising material for environmental remediation and energy-related applications.

Summary: An electrochemical nitrite sensor based on a composite of perovskite oxides La0.8Sr0.2MnO3 (LSM) microspheres-decorated reduced graphene oxide (rGO) was developed, taking advantage of the excellent electrocatalytic activity of LSM and the large surface area of rGO. The sensor with 15 wt% rGO exhibited an ultralow nitrite detection limit of 0.016 mu M and a high sensitivity of 0.041 mu A mu M-1 cm(-2) and 0.039 mu A mu M-1 cm(-2) in the range of 2-100 and 100-5000 mu M, respectively. It also showed good selectivity, reproducibility, and stability, making it suitable for nitrite detection at various pH values. The sensor was successfully applied for the determination of nitrite levels in environmental water samples, demonstrating its feasibility for practical environmental monitoring.

Summary: The study utilized rGO-ZnO for removing Cr (VI) from aqueous medium, which was found to be more economical and promising than GO. The adsorption kinetics followed the pseudo-first-order model, while the equilibrium study showed that the non-linear Langmuir model was a better fit. The calculated maximum adsorption capacities for GO and rGO-ZnO nanocomposite were 19.49 mg/g and 25.45 mg/g, respectively, with endothermic and spontaneous nature of adsorption detected.
