Preparation of Pt/SiO2 ultra-fine particles in reversed micelles and their catalytic activity

摘要

Ultra fine Pt particles supported on SiO2 was successfully prepared by the hydrolysis of tetraethoxysilane in the same reversed micellar solution of previously mono-dispersed Pt particles. Formed Pt/SiO2 surface was partly covered with the residue of surfactant, which caused the inhibition of hydrogen adsorption as well as hydrogenation of propene. [References: 11]
