摘要

Both Ozone (O3) and volatile organic compounds (VOCs) pose substantial risks to human health and ecosystems. Catalytic decomposition of O3 and catalytic ozonation of VOCs are effective degradation strategies. This review elucidates the mechanisms underlying catalytic O3 decomposition and catalytic ozonation of VOCs, while simultaneously establishing the interconnections between these two processes. This review comprehensively delineates the catalysts and control methodologies pertinent to both catalytic O3 decomposition and catalytic ozonation of VOCs, endeavoring to draw parallels between the catalysts employed in these processes. Transition metals, with their versatile valence states and rich electronic structures, exhibit remarkable efficacy in catalytic O3 decomposition and catalytic ozonation of VOCs. Modulating surface structure and concentration of oxygen vacancies emerges as the powerful regulatory strategies. Although the approach to enhancing catalytic ozonation of VOCs parallels that of catalytic O3 decomposition, the intricate environmental context of VOCs necessitates increased focuses on selective adsorption during the initial adsorption phase of the catalyst. Furthermore, a meticulous examination of catalyst stability, especially in relation to resistance against water, sulfur, and chlorine, is imperative. Reactive oxygen species act as pivotal active agents in the catalytic ozonation of VOCs, highlighting the strategic importance of screening catalysts that can generate reactive oxygen species from catalytic O3 decomposition to expedite the degradation of VOCs.
