Abstract

A novel amorphous cobalt tin composite oxide decorated with graphene nanohybrid (CoSn_xO_y/G) sensitized by Eosin Y (EY) exhibited excellent photocatalytic hydrogen evolution activity (974.6 μmol for 3 h) under visible light irradiation. The highest AQE of EY-CoSn_xO_y/G of 20.1% was achieved at 430 nm.
