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.

将二维还原的氧化石墨烯（RGO）固定在氧化锡（SnO ₂）的表面上，以将吸收扩展到可见光区域。SnO ₂和RGO-SnO _2的金红石结构得到确认。通过红外和拉曼光谱技术证实了氧化石墨烯部分还原为RGO。RGO-SnO ₂的载流子重组减少了30％。RGO-SnO ₂的增强的光催化活性可归因于具有较大比表面积的RGO连续网络中的矢量电子转移过程，RGO与SnO ₂之间的协同相互作用，独特的双层特性和光敏过程。通过GC-MS技术鉴定了主要的光催化降解反应中间体。
