▎ 摘　　要

2 dimensional-reduced graphene oxide (RGO) was anchored on the surface of tin oxide (SnO2) to extend the absorption to visible region. Rutile structure is confirmed for SnO2 and RGO-SnO2. Partial reduction of graphene oxide to RGO is confirmed by infrared and Raman spectroscopic techniques. RGO-SnO2 shows 30% reduced recombination of charge carriers. The enhanced photocatalytic activity of RGO-SnO2 can be attributed to vectorial electron transfer process in the continuous network of RGO with large specific surface area, synergistic interaction between RGO and SnO2, unique double layer characteristics and photosensitization process. Major photocatalytic degradation reaction intermediates were identified by GC-MS technique.
