Transition metal doped zeolite as acid/base catalyst for efficient ozone decomposition
Ozone is a major air pollutant at ground level that have detrimental effects on human health and the environment. Catalytic removal of ozone has proven to be the most efficient method. However, its practical application faces substantial challenges, particularly its long-term effectiveness and humidity resistance. Herein, a series of transition metal-doped zeolite catalysts were successfully prepared by the impregnation method for catalytic ozone decomposition. The obtained Co-4A-0.07 catalyst achieving 90% ozone decomposition efficiency over 55 h under a flow rate of 1.4 L⋅min-1 and high-humidity stability, outperforming the Mn, Cu-doped zeolite and Co3O4. The outstanding catalytic performance of Co-4A-0.07 can be attributed to its abundant acid-base sites, which enhanced the capture of ozone, and facilitated the electron transfer within the reaction system, thereby accelerating the catalytic decomposition of ozone. This work offers new perspectives on the rational design of acid-base sites in catalysts to enable efficient ozone decomposition.
期刊介绍:
The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results.
Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
