摘    要:采用水热法制备出具有高比表面积的多层笼状结构的纳米氧化锌.通过XRD,SEM,EDS,TG-DTA,N2吸附等方法对产物的结构、组成、以及形貌进行了表征.以染料甲基橙的光催化降解为模型评价了所得不同形貌的ZnO的光催化活性.结果表明,所得的多层笼状ZnO纳米材料在高压汞灯照射下表现出良好的光催化性能,且多层笼状ZnO的光催化活性优于微米棒.该方法不仅具有工艺简单、绿色环保,且无需引入表面活性剂,便于大规模生产等优点.

关 键 词:高比表面积  纳米氧化锌  笼状结构  光催化剂

Abstract:Multi cage-like zinc oxides were prepared via a facile hydrothermal method.The as-synthesized materials were characterized by means of XRD,TG-DTA,SEM,EDS spectroscopy,N2 adsorption.The photocatalytic activities of ZnO crystals with different morphology were evaluated using degradation efficiency of methyl orange(MO).The results showed that ZnO crystals exhibited good photocatalytic activities under high-pressure mercury vapor lamp irradiation.This method is attractive for its merits such as simplicity,commercial feasibility,environmentally benign,surfactant-free,and good potential for scale-up.
Keywords:high-specific surface  nano zinc oxide  cage-like  photocatalysis
