Abstract Ozone is a highly reactive gas and one of the critical air pollutants for both indoor and outdoor environments. The Occupational Safety and Health Administration (OSHA) determined that the permissible level of ozone is 100 ppb—for 8-h exposure at workplaces. Therefore, using an ozone removal technology can be crucial when outdoor ozone concentration is high and where active ozone emission sources exist. Activated carbon-based filters, catalytic decomposition, and photocatalytic decomposition are air treatment technologies that have been used for ozone removal. The catalytic decomposition approach showed higher efficiency and higher durability with no generation of considerable by-products, particularly manganese oxide (MnOx) based catalysts, which can decompose ozone to oxygen at room temperature. The low cost, as well as high catalytic activity, are among the advantages of MnOx-based catalysts. High specific surface area, high density of oxygen vacancy, high reducibility, and low average oxidation state are desirable properties of the catalyst for ozone decomposition. Despite their excellent performance, their loss of activity in humid conditions challenges their widespread applications. This review presents the recent studies on ozone decomposition technologies, particularly MnOx-based catalysts performance and modification techniques used to improve their performance, and potential future research directions in this field.

用于安全室内环境的主动臭氧去除技术：全面审查

摘要 臭氧是一种高活性气体，是室内和室外环境的关键空气污染物之一。职业安全与健康管理局 (OSHA) 确定允许的臭氧水平为 100 ppb — 在工作场所暴露 8 小时。因此，当室外臭氧浓度高且存在活跃的臭氧排放源时，使用臭氧去除技术至关重要。活性炭基过滤器、催化分解和光催化分解是已用于去除臭氧的空气处理技术。催化分解方法显示出更高的效率和更高的耐久性，并且不会产生大量副产物，特别是基于氧化锰 (MnOx) 的催化剂，它可以在室温下将臭氧分解为氧气。低成本，以及高催化活性，是 MnOx 基催化剂的优势之一。高比表面积、高氧空位密度、高还原性和低平均氧化态是臭氧分解催化剂的理想特性。尽管它们具有出色的性能，但它们在潮湿条件下失去活性对其广泛应用提出了挑战。本综述介绍了臭氧分解技术的最新研究，特别是基于 MnOx 的催化剂性能和用于提高其性能的改性技术，以及该领域未来的潜在研究方向。和低平均氧化态是臭氧分解催化剂的理想特性。尽管它们具有出色的性能，但它们在潮湿条件下的活性丧失对其广泛应用提出了挑战。本综述介绍了臭氧分解技术的最新研究，特别是基于 MnOx 的催化剂性能和用于提高其性能的改性技术，以及该领域未来的潜在研究方向。和低平均氧化态是臭氧分解催化剂的理想特性。尽管它们具有出色的性能，但它们在潮湿条件下的活性丧失对其广泛应用提出了挑战。本综述介绍了臭氧分解技术的最新研究，特别是基于 MnOx 的催化剂性能和用于提高其性能的改性技术，以及该领域未来的潜在研究方向。
