Trends in material innovation for ozone decomposition catalysts

The development trend of ozone decomposition catalyst in material innovation is mainly in the research and development of new carrier materials and the development of multiple composite catalysts.
Research and development of new carrier materials: The carrier can not only improve the dispersion and stability of the catalyst, but also affect the activity of the catalyst. At present, research and development of carrier materials with higher specific surface area, better thermal stability and chemical stability, such as mesoporous materials, nanomaterials, etc. These new carriers can provide more active sites for the catalyst, thus improving the catalytic efficiency. For example, the catalyst prepared with metal oxide supported by mesoporous silica shows excellent ozonolysis performance.
Multi-component composite catalyst development: different metal oxides, precious metals, activated carbon, etc. are combined, and the synergistic effect between each component is used to prepare a multi-component composite catalyst with better performance. This composite catalyst can synthesize the advantages of multiple materials, overcome the limitations of a single material, and have better performance in catalytic activity, stability and selectivity. For example, the CuO-ZnO-Al₂O₃ composite catalyst was highly active in catalyzing ozone oxidation reactions.
