摘要:

单原子催化剂(SACs)以其独特的结构和特性,特别是在最大限度地利用原子和提高内在催化活性方面受到了广泛的关注。 近年来,基于SACs的高级氧化技术(AOPs)已成为水污染控制研究中的一个新兴领域,广泛应用于去除各种难降解有机污染物。 本文分析了SACs的合成及表征方法,着重介绍了SACs在不同类芬顿催化反应中的性能及其作用机理。 此外,还介绍了将SACs固定在膜状或柱状过滤器上连续流的测试,以探究SACs在类芬顿反应中实际应用的潜力。 最后,对合理的SACs设计、类芬顿反应机理探索等方向进行了展望,旨在提高SACs应用于类芬顿反应在实际废水处理中的应用潜力。

Abstract:

Single-atom catalysts (SACs) have attracted much attention due to their unique structure and properties, especially in terms of maximizing the utilization of atoms and improving the intrinsic catalytic activity. In recent years, SAC-based advanced oxidation processes (AOPs) have become a new field in the environmental field, and have been widely used in the removal of various refractory organic pollutants. In this paper, the synthesis and characterization methods of SACs are analyzed, and the catalytic performance of SACs in different Fenton-like catalytic reactions is emphasized. In addition, tests of the continuous flow of SACs fixed on membrane or columnar filters are presented to explore the potential of SACs for practical applications in Fenton-like reactions. Finally, we prospect the future rational SACs design and the exploration direction of the Fenton-like reaction mechanism, aiming to improve the application potential of Fenton-like reaction in practical wastewater.

Key words: Single-atom catalysts, Fenton-like reaction, Degradation of pollutants
