氧化锌是一种高效、无毒性、价格低廉的重要光催化剂。以乙酸锌和草酸为原料，采用溶胶一凝胶法制备纳米ZnO。采用XRD、SEM对纳米ZnO的结构和形貌进行了分析，结果表明，不同焙烧温度下得到的纳米氧化锌均为六方晶系的纤锌矿结构，平均粒径大小在10-55nm。样品颗粒形状基本上为球形，样品颗粒大小比较均匀。以甲基橙溶液为模拟污染物对纳米ZnO的光催化性能进行了研究，结果表明，焙烧温度对纳米氧化锌的光催化性能有一定影响，不同温度下纳米ZnO的光催化效率不同，在焙烧温度450℃时，催化效果较好，可以达到61％。

ZnO is a well-known photocatalyst for its high efficiency, non-toxic nature and low cost. With zinc acetate and oxalic acid as reactants, nano-ZnO is manufactured using sol-gel method. The nano-ZnO structure and morphology are then analyzed by XRD and SEM. The results show that nano- ZnO particles are fine zinc mine hexagon crystalline at various annealing temperatures, their average diameters are uniform at 10 - 55 nm in spherical shape. The light catalytic property was examined by decoloring the simulation methyl orange solution. It finds that annealing temperature influences the photocatalytic property of nano-ZnO, and the decoloring efficiency is dependant on the annealing temperature, which reaches maximum of 61% at annealing temperature of 450℃.
