Pt/titania/reduced graphite oxide nanocomposite: An efficient catalyst for nitrobenzene hydrogenation

► Pt/TiO2/RGO was obtained by immobilizing Pt particles onto TiO2/RGO. ► TiO2/RGO was prepared via redox reaction between TiCl3 and GO. ► Pt/TiO2/RGO showed high activity and selectivity for nitrobenzene hydrogenation. ► The catalyst can be reused for six times without any activity loss.
