Photoelectrochemical hydrogen generation at hybrid rGO-Sn3O4/SnO2 nanocomposite
This study investigates the photoelectrocatalytic water splitting at Sn 3 O 4 and ternary rGO-Sn 3 O 4 /SnO 2 heterostructure nanocomposite materials. The nanocomposite exhibited superior performance compared to Sn 3 O 4 , a result which was related to stronger absorption in the visible region, narr...
