Summary: In this study, a plant mediated synthesis method was used to prepare Metal/metal oxide@Reduced graphene oxide nanocomposites, including silver, gold, and zirconia. These nanocomposites showed high catalytic activity in Suzuki cross-coupling reaction between aryl halides and phenylboronic acid, achieving comparable yields to palladium-based catalysts. The enhanced reactivity of the reduced graphene oxide substrate contributed to the successful coupling reaction.

Summary: This study synthesized and characterized three different nanocomposite materials, including silver and zinc oxide nanoparticles modified reduced graphene oxide (rGO), and rGO modified with both silver and zinc oxide nanoparticles. These materials were characterized using XRD, FTIR, TGA, Raman spectroscopy, SEM, and TEM techniques. The electrochemical responses of these materials towards the standard ferrocyanide/ferricyanide [Fe(CN)6]3-/4- redox system were investigated using CV and EIS techniques. The results showed that ZnO modified rGO exhibited excellent electrochemical performance, attributed to the high surface area of ZnO, providing a larger electrode/electrolyte interface and more sites at the electrolyte-ZnO interface.

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.

Summary: In this study, a dual-signal sensor for H2O2 determination was fabricated using 2D Cu-MOFs decorated with Ag NPs. A novel polydopamine reduction method was employed to reduce [Ag(NH3)(2)](+) to highly dispersed Ag NPs in situ without other reductive agents, resulting in Cu-MOF@PDA-Ag. The sensor exhibited excellent electrocatalytic properties and a colorimetric platform for the detection of H2O2.

Summary: In this study, Ag nanoparticles were photoreduced onto graphene oxide or reduced graphene oxide-TiO2 nanocomposites. Characterization using SEM-EDS, XPS and Raman spectroscopy showed that AgNPs were distributed on the surface of TiO2 and on graphene oxide or reduced graphene oxide flakes. The research revealed significant differences in the size and distribution of AgNPs grown on TiO2 and on areas covered by graphene oxide or reduced graphene oxide.

Summary: A dual-templating method is developed to fabricate graphene oxide (GO) scaffolds with interconnected hierarchical porosity for bone tissue engineering. The method involves freezing and drying high internal phase emulsions stabilized by GO sheets, resulting in the templating of large and small pores by oil droplets and ice crystals, respectively. This approach enables the synthesis of complex hierarchical architectures in reduced graphene oxide (rGO) and GO composite scaffolds.
