英文摘要： The highly efficient heterogeneous catalyst for hydrosilylation will be assembled based on special physical and chemical properties of supermicroporous molecular sieves. The synthesis route of supermicropore SiO2 is Propose through silane constracted reaction. Active metal precursor in namopore will be coated and uniformly dispersed orderly by coordination of heteroatom on organosilane and selective affinity on metalled salt by solvent micelle vesicles inside. The particular catlysis of nano active particle will be studied in nanopore confinement microenvironment. The process and mechanism in regio and stereoselective hydrosilylation will be investigated in heterogeneous catalysis of supermicropore molecular sieves. The related theory and technology will be created in environmentally friendly and highly efficient heterogeneous hydrosilylation catalyst area. so it will have important theoretical value and broad application prospects.
