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。研究结果表明不管是紫外光照下还是蓝光光照下,随着光强的增大,ZnO/WO3复合材料对甲基橙的降解率都呈现出先增大后减小的趋势,光强为62 W/m2时降解率最大。而在相同光强光照下,紫外光比蓝光的降解效果好。 ZnO/WO3 photocatalytic composite electrode was prepared with the ball - milling method and screen - printing technology. The results showed that with the increase of the photo intensity, the photoelectrocatalytic efficiency of ZnO/WO3 composite was first increased, then decreased. When the photo intensity was 62 W/m^2, the decomposition of methyl orange got the maximum. With the same photo intensity, the decomposition efficiency under UV light was higher than that under blue light.
