Abstract

Abstract With the rapid development of urbanization and industrialization, environmental pollution has become more severe. Volatile organic compounds (VOCs) could be originated from the following sources: domestic, mobile and industrial sources. As important air pollutants, VOCs could cause serious harm to the environment and human health. Therefore, removing VOCs has become a priority research direction of ecological issues. Among the many elimination methods, catalytic oxidation approaches are among the most effective and economical methods which can transform VOCs into CO2 and H2O. MnOx catalysts are among the most active catalysts, which can be further modified by different cations such as Cu2+, Co2+, Cr3+, Ni2+ and Ce4+ to form mixed oxides to improve the catalytic oxidation of VOCs activity. Moreover, MnOx can be loaded on the carrier, improving the redox and oxygen storage capacity and improving its stability and activity. This review explores the structure, preparation and oxidation state of Mn-based catalysts.

锰基催化剂催化氧化挥发性有机物的研究进展

随着城市化和工业化的快速发展，环境污染日益严重。挥发性有机化合物(VOCs)可能来自以下来源:家庭、移动和工业来源。挥发性有机化合物是重要的大气污染物，对环境和人体健康造成严重危害。因此，去除挥发性有机化合物已成为生态问题的优先研究方向。在众多的消除方法中，催化氧化法是将VOCs转化为CO2和H2O的最有效和最经济的方法之一。MnOx催化剂是活性最高的催化剂之一，可以通过Cu2+、Co2+、Cr3+、Ni2+、Ce4+等不同阳离子进一步改性，形成混合氧化物，提高催化氧化VOCs的活性。此外，MnOx可以装载在载体上，提高了载体的氧化还原和储氧能力，提高了载体的稳定性和活性。本文综述了锰基催化剂的结构、制备方法和氧化态。
