摘要
近年来,在传统催化材料的研究基础上,伴随着矿物材料应用的不断发展,催化材料和矿物材料的研究者们认识到矿物经过处理后可以作为催化剂或者催化剂载体使用。锰矿、稀土矿、铁矿、蒙脱石、高岭土、坡缕石等,在经过一系列物理化学方法处理后可用于制备催化剂且有较好的催化性能。一部分金属氧化物矿物具有较好的氧化还原能力,用来做催化剂的活性组分;而另一部分矿物因其具有一定的特性,如比表面积大、孔隙结构丰富和能提供酸位点等优点,可以用来做催化剂的载体。上述矿物经过长期的地质演变形成特殊的物理结构和存在状态,充分挖掘矿物原有的表面性质、活性位点、价键形态等微观信息,并通过一系列的改性处理方法,可制备出高效绿色的催化产品。
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.
