采用简单的化学共沉淀法成功制备了铝掺杂氧化锌(AZO)导电粉体。采用X射线粉末衍射(XRD)、扫描电子显微镜(SEM/EDS)和动态光散射(DLS)对不同煅烧气氛下的粉体进行了表征。以水溶液中的橙子(MO)为目标降解物,研究了其光催化活性随催化剂选择性的变化规律。结果表明,甲基橙子染料的光降解符合准一级动力学反应规律,AZO光催化活性与不同煅烧气氛下样品的电阻率有关。
Aluminum-doped zinc oxide (AZO) conductive powders have been successfully prepared by a simple chemical coprecipitation method. The obtained powders with different post-calcining atmospheres were characterized using X-ray powder diffraction (XRD), scanning electron microscopy (SEM/EDS), and dynamic light scattering (DLS). The resistivity-dependent photocatalytic activity was studied by degradation of methyl orange (MO) in aqueous solution. The result showed that photodegradation of methyl orange dyes obeyed the rule of a pseudo first-order kinetics reaction and the AZO photocatalytic activity was related to the resistivity under different post-calcining atmospheres.
