摘　　要：采用水热法成功制备了Bi_(2)MoO_(6)/TiO_(2)/GO复合材料,该材料在可见光照射下对罗丹明B具有高催化活性。可见光照射120 min,TiO_(2)掺杂比为10%,投加量为0.15 g时,Bi_(2)MoO_(6)/TiO_(2)/GO复合材料对罗明丹B光催化降解率达100%。可见光的催化条件和高的催化性能,使Bi_(2)MoO_(6)/TiO_(2)/GO复合材料在环境处理方面具有广阔的应用前景。Bi_(2)MoO_(6)/TiO_(2)/GO composite was successfully prepared by hydrothermal method.It had high photocatalytic activity for Rhodamine B(RhB)under visible light instead of ultraviolet light irradiation.Experimental results showed that the photocatalytic degradation rate of RhB by Bi_(2)MoO_(6)/TiO_(2)/GO composite was100%when the doping ratio of TiO_(2)in the composite was 10%,the dosage was 0.15 g,and the irradiation time with visible light was 120 min.Therefore,Bi_(2)MoO_(6)/TiO_(2)/GO composite had a good application prospect in practical environmental treatment due to its visible light catalytic condition and high catalytic performance.
