研制了一种用于氧化降解水中持久性有机化合物的氯化铁（FeOCl）催化剂。H2O2分解产生羟基自由基（OH.）的活性非常高，比其他铁基非均相催化剂高2-4个数量级。采用XRD、HRTEM、EPR等多种技术建立了催化剂结构与性能的关系。铁原子的独特结构和FeOCl的可还原电子性质是其具有优异活性的原因。本研究为合理设计相关催化剂应用于废水处理、土壤修复等新兴环境问题铺平了道路。
An iron oxychloride (FeOCl) catalyst was developed for oxidative degradation of persistent organic compounds in aqueous solutions. Exceptionally high activity for the production of hydroxyl radical (OH.) by H2O2 decomposition was achieved, being 2-4 orders of magnitudes greater than that over other Fe-based heterogeneous catalysts. The relationship of catalyst structure and performance has been established by using multitechniques, such as XRD, HRTEM, and EPR. The unique structural configuration of iron atoms and the reducible electronic properties of FeOCl are responsible for the excellent activity. This study paves the way toward the rational design of relevant catalysts for applications, such as wastewater treatment, soil remediation, and other emerging environmental problems.
