The severe hazard of chlorinated volatile organic compounds (CVOCs) to human health and the natural environment makes their abatement technology a key topic of global environmental research. Due to the existence of Cl, the byproducts of CVOCs in the catalytic combustion process are complex and toxic, and the possible generation of dioxin becomes a potential risk to the environment. Well-qualified CVOC catalysts should process favorable low-temperature catalytic oxidation ability, excellent selectivity, and good resistance to poisoning, which are governed by the reasonable adjustment of acidity and redox properties. This review overviews the application of different types of multicomponent catalysts, that is, supported noble metal catalysts, transition metal oxide/zeolite catalysts, composite transition metal oxide catalysts, and acid-modified catalysts, for CVOC degradation from the perspective of balance between acidity and redox properties. This review also highlights the synergistic degradation of CVOCs and NO_x from the perspective of acidity and redox properties. We expect this work to inspire and guide researchers from both the academic and industrial communities and help pave the way for breakthroughs in fundamental research and industrial applications in this field.

多催化剂催化氯化挥发性有机化合物氧化的新进展：酸度和氧化还原性质的合理调节

氯化挥发性有机化合物（CVOCs）对人类健康和自然环境的严重危害，使其减排技术成为全球环境研究的重点课题。由于Cl的存在，CVOCs在催化燃烧过程中的副产物复杂且有毒，可能产生的二恶英成为对环境的潜在风险。合格的CVOC催化剂应具有良好的低温催化氧化能力、优良的选择性和良好的抗毒性，这取决于酸度和氧化还原性能的合理调整。本综述概述了不同类型多组分催化剂的应用，即负载型贵金属催化剂、过渡金属氧化物/沸石催化剂、复合过渡金属氧化物催化剂、从酸度和氧化还原性能平衡的角度来看，酸改性催化剂用于CVOC降解。这篇综述还强调了 CVOC 和 NO 的协同降解_x从酸度和氧化还原性质的角度来看。我们希望这项工作能够启发和指导学术界和工业界的研究人员，并为该领域基础研究和工业应用的突破铺平道路。
