摘要
通过一步热解Zn1−Cu (HCOO)(OCH2CH2O)1/2配合物，得到Zn1−Cu O固溶体。这些材料中的Сopper是聚集体的光活性和形态的调节剂。根据TEM, XPS，光谱学和伏安法，所有样品都含有一价铜。结果表明，紫外光和蓝光下As光氧化反应的最大光活性为Zn1−Cu O (0本文章由计算机程序翻译，如有差异，请以英文原文为准。
Copper-doped quasi-one-dimensional ZnO for effective photooxidation of As (III) to As (V) in visible light
By temolysis of the Zn1− Cu (HCOO)(OCH2CH2O)1/2 complexes in one step Zn1− Cu O solid solutions were obtained. Сopper in these materials is a regulator of the photoactivity and morphology of aggregates. According to TEM, XPS, optical spectroscopy, and voltammetry, all samples studied contain monovalent copper. It was shown that the maximum photoactivity in the reactions of photooxidation of As in UV and blue light has Zn1− Cu O (0
