ZnFe2O4 nanoparticles (ZFNPs) were developed as catalyst for the degradation of benzotriazole (BTA) by heterogeneous photoelectro-Fenton (PE-Fenton) like process. ZFNPs were prepared by a co-precipitation process and then characterized with transmission electron microscopy (TEM), X-ray fluorescence (XRF), X-ray diffraction (XRD) and BET surface area. Using such ZFNPs as catalyst, the degradation of BTA was investigated. Due to the high catalytic activity of ZFNPs, PE-Fenton like process showed efficient degradation of BTA. The influencing factors such as pH, dosage of ZFNPs, applied potential and initial concentration of BTA were systematically investigated. Under the optimum conditions, 91.2% of BTA was removed after 180 min treatment.
ZnFe2O4 纳米粒子 (ZFNPs) 被开发为用于通过非均相光电芬顿 (PE-Fenton) 类似过程降解苯并三唑 (BTA) 的催化剂。ZFNPs 通过共沉淀法制备，然后用透射电子显微镜 (TEM)、X 射线荧光 (XRF)、X 射线衍射 (XRD) 和 BET 表面积进行表征。使用这种 ZFNPs 作为催化剂，研究了 BTA 的降解。由于 ZFNPs 的高催化活性，PE-Fenton 类似过程显示出对 BTA 的有效降解。系统研究了影响因素，如 pH 值、ZFNPs 用量、施加的电势和 BTA 的初始浓度。在最佳条件下，经过 180 分钟处理，BTA 的去除率达到 91.2%。
