摘要

摘要本文介绍了高温热解合成的氧化锌四元晶的结构和形态特征以及发光和光催化性能的研究结果。研究表明，氧化锌四元体的形态和结构参数是由合成区的位置决定的。所有样品都具有四元晶的假三维形态特征。研究发现，四元结晶的发光特性与光催化活性之间存在相关性。在紫外线辐射下，生长在离进气口窗口最近和最远区域的氧化锌四元柱对亚甲蓝的光降解率最高（速率常数分别为 54 × 10-3 和 50 × 10-3 min-1）。

Characterization and Photocatalytic Properties of ZnO Tetrapods Synthesized by High-Temperature Pyrolysis

Abstract

This work presents the structural and morphological characterization and the results of studies of the luminescence and photocatalytic properties of ZnO tetrapods synthesized by high-temperature pyrolysis. It was demonstrated that the morphology and structural parameters of ZnO tetrapods are defined by the location in the synthesis zone. All samples are characterized by pseudo-three-dimensional morphology of tetrapods. The correlation was found between the luminescence properties and photocatalytic activity of tetrapods. The highest photodegradation rates of methylene blue under UV radiation were demonstrated by ZnO tetrapods grown in the zones closest to and farthest from the air-inlet window (the rate constants were 54 × 10^–3 and 50 × 10^–3 min^–1, respectively).
