摘　　要：利用水热法合成层状氧化锌,通过加入蔗糖作为络合剂和助燃剂促使样品的微观结构发生变化.利用XRD、SEM对样品进行了表征.利用有机染料甲基橙的降解对产物的光催化性能进行了评价,实验表明蔗糖辅助合成的氧化锌表现出更高的降解性能.研究结果表明高结晶质量使得样品具有高效的光催化性能,并且,讨论了蔗糖的量对氧化锌光催化性能的影响.In this paper, hierarchical ZnO flowers are assisted the combustion during annealing, leading synthesized via a hydrothermal method. Sucrose as a fuel to the improvement of the microstructure of samples. ZnO flowers are characterized by XRD and SEM. Photocatalytic activity is evaluated using the degradation of organic dye methyl orange. The sucrose added ZnO flowers show improved activity, which is mainly attributed to the better crystallinity as confirmed by XRD analysis. The effect of sucrose amount on photocatalytic activity is also studied.
