Is copper the key to cleaner indoor air? This review explores the increasing concern over ozone in enclosed environments and the potential of copper-based catalysts for ozone decomposition. Highlighting their superior performance and relatively low cost, the review examines recent studies on Cu catalysts, particularly morphological design, heterostructure construction, and monolithic catalyst design, all aimed at enhancing performance. The review presents a comprehensive overview of current research, addressing the inherent limitations of Cu materials and practical needs. It emphasizes the need for morphological design, the construction of heterostructures, and monolithic catalyst design to improve their performance. Ultimately, the review proposes future improvement directions for Cu materials and anticipates a growing role for these catalysts in ozone decomposition technologies. This work provides valuable insights for researchers and engineers working to improve air quality in indoor spaces and enclosed environments.
