Probing the Catalytic Activity of Reduced Graphene Oxide Decorated with Au Nanoparticles Triggered by Visible Light.
Hybrid materials in which reduced graphene oxide (rGO) is decorated with Au nanoparticles (rGO-Au NPs) were obtained by the in situ reduction of GO and AuCl4(-)(aq) by ascorbic acid. On laser excitation, rGO could be oxidized as a result of the surface plasmon resonance (SPR) excitation in the Au NPs, which generates activated O2 through the transfer of SPR-excited hot electrons to O2 molecules...
متن کاملAssessment of antioxidant and antibacterial activities of Zinc Oxide nanoparticles, Graphene and Graphene decorated by Zinc Oxide nanoparticles
Zinc Oxide nanoparticles (ZnO-NPs) and graphene carbon material, due to lower drug resistance, can replace antibiotics, and by decorating of graphene with Zn-NPs, their properties can be greatly improved. The purpose of this study was to evaluate the antioxidant and antibacterial effects of ZnO-NPs biosynthesized using Crocus Sativus petal extract, graphene and graphene decorated by ZnO-NPs bio...
متن کاملEnhanced conductivity of reduced graphene oxide decorated with aluminium oxide nanoparticles by oxygen annealing.
A process involving the filtration of graphene oxide (GO) dispersion through an alumina membrane, followed by oxygen annealing to synthesize alumina nanoparticles exclusively at the edges of holes or vacancies in the reduced graphene oxide (rGO) plane, is used to prepare paper-like composites with a 21% enhanced electrical conductivity. Moreover, the rGO/alumina nanocomposites have a smaller ba...
متن کاملFacile hydrothermal preparation of titanium dioxide decorated reduced graphene oxide nanocomposite
A simple single-stage approach, based on the hydrothermal technique, has been introduced to synthesize reduced graphene oxide/titanium dioxide nanocomposites. The titanium dioxide nanoparticles are formed at the same time as the graphene oxide is reduced to graphene. The triethanolamine used in the process has two roles. It acts as a reducing agent for the graphene oxide as well as a capping ag...
متن کاملMoS2 nanoflower-decorated reduced graphene oxide paper for high-performance hydrogen evolution reaction.
A facile, one-pot solvothermal method is developed to synthesize MoS2 nanoflowers (MoS2NFs) coated on reduced graphene oxide (rGO) paper. The resulting MoS2NF/rGO paper serves as a freestanding, flexible and durable working electrode for hydrogen evolution reaction (HER), exhibiting an overpotential lowered to -0.19 V with a Tafel slope of ∼95 mV per decade.
