采用两步湿化学方法制备了还原氧化石墨烯（RGO）接枝W掺杂BiVO4（WBVO）杂化物。首先采用水热法在强酸条件下合成了WBV。其次，在乙醇-水条件下，通过水热处理将WBVO/GO混合物转化为WBVO/RGO混合物。将RGO的含量控制在4 wt%，可优化WBV/RGO的光催化活性。这种新型复合光催化剂在空气净化和废水处理方面具有潜在的应用前景。
Reduced graphene oxide (RGO) grafted W doped BiVO4(WBVO) hybrids have been obtained using two-step wet-chemical approach. At first, WBV was synthesized by hydrothermal method in strong-acid condition. And second, the WBVO/GO mixture was transformed into WBVO/RGO hybrids by hydrothermal treatment under ethanol–water condition. The photocatalytic activity of WBV/RGO can be optimized by controlling the content of RGO at 4 wt%. Such a novel composite photocatalyst might find potential application for air purification and waste water treatment.
