Abstract Graphene oxide (GO) is a monolayer of oxidized graphene which convenient and potential candidate in wide range fields applications like electronics, photonics, optoelectronics, energy storage, catalysis, chemical sensors, many others. GO often composed various oxygen-containing groups such as hydroxyl, carboxyl, epoxy. One appealing method for achieving graphene-like behavior with sp 2 hybridized carbon the reduction i.e. formation reduced (RGO). A stepwise to form family RGO, containing quantities oxygen-related defects was carried out. Herein, related physical properties RGO were studied reported an effort understand how vary rate. Although there are several reports on features but systematic investigation variation varying oxygeneous imperative engineered desired field applications. We have attempted look at role 3 fractions, present RGO-based systems, they affect electrical, optoelectronic, adsorption characteristics.

A visible-light-responsive photocatalyst, comprising reduced graphene oxide (RGO) modified tin selenide (SnSe), was fabricated via a cost-effective, one-pot, easy-to-achieve, single-step solvothermal method. The Brunauer–Emmett–Teller analysis shows SnSe with specific surface area of about 0.3 m2 g–1, while RGO–SnSe significantly increases it to 8.44 g–1. photocatalytic kinetics the composite revealed pseudo-first-order reaction mechanism during degradation norfloxacin antibiotics in an aqueous environment. Results indicated that increase RGO content composites led enhanced efficiency and apparent quantum yield, reaching maximum values 90.7 11.37%, respectively, at loading 37 wt %. These were found be 3.6 times higher than pure SnSe. However, further augmentation resulted decline both yield. catalytic performance can attributed improved synergy between electrical energy per order calculated assess process, yielding low value 6.7 kW h m−3/order for 0.75 mg/L catalyst. activity remained nearly unchanged least four repeated cycles without any This outcome underscores efficacy as efficient sustainable technique antibiotic high yield consumption.
