摘　　要：利用太阳能解决环境污染问题是当今世界的研究热点,氧化锌(ZnO)作为经典的半导体材料在光催化降解有机污染物领域研究甚广。本文从催化剂有效回收的角度考虑,摒弃传统的ZnO粉末状催化剂,通过多种制备方案在透明的玻璃基片上制备不同形貌的ZnO阵列光催化剂,实验结果表明,ZnO纳米棒阵列具有更高的光降解活性,2h后罗丹明B的脱色率达到100%。这种兼具高活性及易回收性质的阵列催化剂为水污染治理提供了新的思路。Using solar energy is the research hotspot to solve environmental pollution problems nowadays. Zinc oxide(ZnO)as a classic of semiconductor materials, there are research widely in the field of photocatalytic degradation of organic pollutants. This paper is from the perspective of effective catalyst recycling, instead of the traditional ZnO powder catalyst, different morphology of ZnO arrays had been prepared in transparent glass substrate through a variety of preparation plan. The results show that ZnO nanorod array had a higher photodegradation activity, decoloring rate of the rhodamine B reached 100% after 2 hours. Properties of photocatalysts with highly active array and easy recycling provides a new thought for water pollution.
