Abstract: In recent years, on the basis of traditional catalytic materials and with the continuous development of the application of mineral materials, researchers have realized that some kinds of minerals can be used as catalysts or supports after treatment. Metal oxide minerals such as manganese ore, rare earth ore and iron ore, as well as non-metal oxide minerals such as montmorillonite, kaolin, palygorskite treated with physical and chemical methods, can be used to prepare denitration catalysts with better catalytic performance. Metal oxide minerals with good redox ability, canbe used as active components of catalysts. Minerals with certain characteristics: such as large specific surface area, rich pore structure, providing acid sites, can be used as a catalyst carrier. The above-mentioned minerals have formed a special physical structure and state of existence through long-term geological evolution. The original surface properties, active sites, valence bond forms and other microscopic information of the minerals can be fully excavated, and through a series of modification treatment methods, green catalytic products with high-efficiency can be prepared.
