Title

Enhanced Visible Light Hydrogen Production of Reduced Graphene Oxide Incorporated Metal Oxide Nanocomposites

Abstract

This study presents a novel method for the synthesis of titanium dioxide (TiO2)/reduced graphene oxide (RGO) nanocomposite photocatalyst and study the H2 production rate under solar light. The prepared photocatalysts were analyzed for their microstructure, morphology, optical, and textural properties through XRD, TEM, Raman, UV, PL and BET analysis. XRD results suggest that both pure and RGO incorporated TiO2 samples show anatase phase tetragonal rutile type crystalline structure. TEM pictures clearly show the spherical shaped nanoparticles of TiO2 ranged in sizes from 30-40 nm, which are further decorated uniformly on the RGO sheets surface. When the ratio of RGO is 0.25 wt%, the highest H2-production rate was achieved. It increased by 10-fold than bare TiO2, reaching 1419 μmol h−1g−1 with quantum efficiency (QE) of 5.75%. The reasons were as follows. Firstly, the RGO nanosheets acted as electron acceptors. Secondly, some shallow trap states at the surface or interface of TiO2 were created by the reduction of GO during calcination.
