Eddy Current Induced Piezoelectric Promotes ZnO Photodegradation of Potassium Butylxanthate

以硝酸锌和氨水为前驱体,使用低溶液温法在柔性基体尼龙网上生长ZnO纳米阵列。通过扫描电镜、X射线衍射、紫外光谱、红外光谱等对所制备光催化剂的结构和形貌进行测试。结果表明,ZnO纳米阵列呈六边形棒状形貌,晶体结构为六方铅锌矿,在紫外区有很好的光吸收性能。在搅拌条件下溶液产生涡流,诱导ZnO纳米阵列产生压电效应,提高了紫外光照条件下丁基黄原酸钾溶液的降解效果。光照90 min丁基钾黄药的降解率达95.34%,比单纯光照条件提升了44.62%。

A low-temperature method solution was used to grow ZnO nanoarray photocatalysts on a flexible base nylon mesh by using zinc nitrate and ammonia as precursors.The structure and morphology of the prepared photocatalyst were tested by scanning electron microscopy,X-ray diffraction,ultraviolet spectroscopy,infrared spectroscopy and other test methods.The results show that the ZnO nano-array has a hexagonal rod-like structure and the crystal structure is hexagonal lead-zinc ore,which has good light absorption performance in the ultraviolet region.By generating a vortex under the condition of solution stirring,the ZnO nanoarray is induced to produce a piezoelectric effect,and the degradation effect of potassium butylxanthogenate solution under ultraviolet light conditions is improved.Under stirring conditions,the degradation rate of butyl potassium xanthate can be reached for 90 min of light 95.34%,better than the light conditions alone 44.62%.
