摘要
通过柠檬酸络合法+浸渍法合成B+Mo共掺杂Bi VO4,并对其进行XRD、SEM和UV-vis表征,研究合成材料的物相、形貌和光吸收性能。将制备的样品用于光催化降解罗丹明B,考察了溶液的初始浓度、p H、催化剂投加量等因素对光催化降解罗丹明B的影响。实验结果表明:罗丹明B的初始浓度为15 mg/L、p H=5、催化剂投加量为0.015 g时,B-Mo共掺杂Bi VO4对罗丹明B有较好的光催化活性,反应50 min后,降解率可达91%以上。
B and Mo co-doped BiVO4 visible-light-driven photocatalysts have been synthesized by citric acid complex method and impregnation method. It was characterized by XRD, SEM and Uv-vis. The effects of the initial concentration, the pH value, and the dosage of catalyst on the degradation of Rhodamine B under simulated solar light irradiation are studied. The result shows that B-Mo co-doped BiVO4 has the best photocatalytic activity on Rhodamine B degradation under the conditions of initial Rhodamine B concentration of 15 mg/L, pH value be 5, and 0.015 g dosage of catalyst, the removal efficiency of Rhodamine B can be more than 91% after 50 min irradiation.
