摘要
通过球磨法和丝网印刷技术,制备得到了WO3质量分数为50%的ZnO/WO3复合光催化电极。当偏压从0 V增加到3 V时,ZnO/WO3复合材料对甲基橙的降解率先增加后减小,在1 V时,降解率出现极大值。继续增加电压到4 V时,ZnO/WO3复合材料对甲基橙的降解率急剧增加。
ZnO/WO3 photocatalytic composite electrode was prepared with the ball-milling method and screen-printing technology. The results showed that when the bias potential increased from 0 V to 3 V+ the pbotoelectrocatalytic efficiency of ZnO/WO3 composite first increased, then decreased. When the bias intensity was 1V, the decomposition efficiency of methyl orange got maximum. Continue to increasing the bias potential to 4 V, the photoelectrocatalytic efficiency of ZnO/WO3 composite increased dramatically.
