摘　　要：介孔材料由于其同时具备较高的比表面积、适宜的孔容和孔径分布、合适的粒径分布和机械强度等特点,被广泛应用于传感、组织工程、催化、离子电池和太阳能电池等领域。介孔二氧化硅材料SBA-15分子独特的空间结构,可与小分子结合,使其在环境科学、催化、医药工业等领域被广泛应用。文中借助和发挥介孔氧化硅SBA-15载体自身的优异特性及其与活性组分之间的相互作用,实现负载型后过渡金属催化剂的高性能化。Mesoporous materials are widely used in sensing, tissue engineering, catalysis, ion batteries, solar cells and other fields because of their high surface area, suitable pore volume and pore size distribution, suitable particle size distribution and mechanical strength. The unique spatial structure of mesoporous silica material SBA-15, which can be combined with small molecules, makes it widely used in environmental science, catalysis, pharmaceutical industry and other fields. In this paper, by virtue of the excellent properties of mesoporous silica SBA-15 support and its interaction with active components, the high performance of supported late-transition metal catalyst was realized.
