Abstract
Manganese-based catalysts have attracted much attention in the field of degradation of volatile organic compounds (VOCs) due to low cost, long durability, structural diversity and high efficiency. In addition, defect engineering plays an important role in the modification of manganese-based catalysts, especially for the contribution of active sites and specific surface area. Therefore, this study reviews the recent research progress achieved in engineering the defects of manganese-based catalysts for practical applications in VOCs. Firstly, the classification and synthesis methods of defects in manganese-based catalysts are provided. Secondly, characterization techniques for the identification of defects are highlighted, and then current research on the application of manganese-based catalysts for the catalytic oxidation of VOCs is presented. Finally, future challenges and prospects for defect engineering of manganese-based catalysts are discussed to further promote optimal catalyst design and industrial applications.
期刊介绍：
Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
