摘要

本研究考察了掺锌镉铝铁氧体 ZnxCdX-1Al0.1Fe1.9O4 (X = 0,0.3) 纳米粒子的合成、表征和光催化活性,用于降解阿特拉津。纳米粒子通过溶胶-凝胶法合成,并利用 X 射线衍射 (XRD)、扫描电子显微镜 (SEM)、能量色散 X 射线光谱 (EDX) 和紫外可见光漫反射光谱等多种技术对其结构、形态和光学性质进行了表征。评估了合成纳米粒子在可见光照射下的光催化活性,并研究了各种参数的影响,如 Zn 掺杂浓度、初始阿特拉津浓度、pH 值、温度、催化剂剂量、光照强度和过氧化氢(H2O2)的添加。结果表明,在正常条件下,掺杂锌的镉铝铁氧体对阿特拉津的降解能力明显增强,与未掺杂的镉铝铁氧体的 75% 相比,去除率达到 93%。清除剂分析表明,羟基自由基(OH˙)在光降解过程中发挥了关键作用。这些发现有助于开发高效、可持续的光催化剂,用于降解阿特拉津和其他有机污染物。

Synthetic studies of zinc-doped cadmium aluminum ferrite for the photocatalytic degradation of atrazine

In this study, the synthesis, characterization, and photocatalytic activity of zinc-doped cadmium aluminum ferrite ZnxCdX−1Al0.1Fe1.9O4 (X = 0,0.3) nanoparticles were investigated for the degradation of atrazine. The nanoparticles were synthesized via a sol–gel method, and their structural, morphological, and optical properties were characterized using various techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and UV–Vis diffuse reflectance spectroscopy. The photocatalytic activity of the synthesized nanoparticles was evaluated under visible-light irradiation, and the influence of various parameters, such as Zn doping concentration, initial atrazine concentration, pH, temperature, catalyst dose, light intensity, and addition of hydrogen peroxide (H2O2), was investigated. The results demonstrated a significant enhancement in atrazine degradation with Zn-doped cadmium aluminum ferrite, achieving a removal efficiency of 93% compared with 75% for undoped cadmium aluminum ferrite at normal conditions. Scavenger analysis suggested that hydroxyl radicals (OH˙) played a crucial role in the photodegradation process. These findings contribute to the development of efficient and sustainable photocatalysts for the degradation of atrazine and other organic pollutants.
