Graphene has many excellent properties such as wide specific surface area, outstanding electrical mobility, and high optical transmittance. Due to these advantages, which make graphene appropriate matrix supporting vanadium for the nanocomposite. Also, depending on the synthesis process, graphene can be obtainable graphene oxide (GO) and reduced graphene oxide (RGO). Moreover, RGO has been receiving increased attention due to its nature to easily reduced to graphene, referred to as RGO, which has wide application. The purpose of this study is to investigate the characteristic of V2O5 deposited on RGO. The nanocomposite of vanadium oxide (V2O5) supported on RGO was prepared by different methods of evaporation, impregnation and impregnation with dispersant. XRD, SEM, TEM, BET and TGA analyses were used to investigate their chemical stability, and amount in vanadium oxide on RGO. This synthesis of V2O5 supported RGO is expected to be used as selective catalytic reduction (SCR) catalyst for De-NOx.
