摘　　要：采用简单的化学溶液生长法,在Ag棒表面包覆生长一层ZnO纳米棒阵列.利用该结构光电催化降解罗丹明B,其效率远高于电降解和自降解,约为光催化降解的2倍,表明外加电压能有效提高催化剂的光催化效率.研究了不同工作电极间距对催化效率的影响,结果表明,最佳电极间距约为1.0 cm.A layer of ZnO nanorod arrays was grown on the Ag micro-rod surface by a simple chemical so-lution method. The photoelectrocatalytic degradation efficiency of the ZnO structures for Rhodamine B was higher than that of the electro-degradation and self-degradation. It was about twice that of photocata-lytic degradation efficiency, indicating that the applied voltage could effectively improve the catalytic effi-ciency of the catalyst. The influence of the different working electrode distance on the catalytic efficiency was studied. The results showed that the optimum electrode distance was about 1. 0 cm.
