摘要

本文研究了低温湿化学法制备的氧化锌异质结构的光催化活性。用原子力显微镜对其结构进行了研究,发现颗粒的大小在50 ~ 150 nm之间。采用甲基橙有机染料对可见光区光进行吸附,研究了异质结构的光催化活性。用紫外光照射负载光催化剂的染料溶液,用紫外-可见分光光度计监测染料的浓度变化。

Photocatalytic Activity of Zinc Oxide Based Heterostructures
In this work we perform the study of photocatalytic activity of zinc oxide based heterostructures obtained by the low-temperature wet chemistry method. The structures were studied by atomic-force microscopy and it was found that the size of the particles varies from 50 nm to 150 nm. The photocatalytic activity of the heterostructures was studied using methyl orange organic dye that adsorbs light in visible region. The dye solution with photocatalyst loaded was irradiated with ultra-violet light and the concentration changes of the dye were monitored using UV-Vis spectrophotometer.
