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.
开发了一种氧氯化铁 (FeOCl) 催化剂，用于氧化降解水溶液中的持久性有机化合物。该催化剂在 H2O2 分解生成羟基自由基 (OH·) 方面表现出极高的活性，比其他基于铁的多相催化剂高 2-4 个数量级。通过使用 XRD、HRTEM 和 EPR 等多种技术，建立了催化剂结构与性能之间的关系。铁原子的独特结构构型和 FeOCl 的可还原电子性质是其具有优异活性的原因。本研究为相关催化剂的合理设计开辟了道路，可应用于废水处理、土壤修复和其他新兴环境问题等领域。
