  • Method for making monodispersed noble metal nanoparticles supported on oxide substrates
    Patent number: 6992039
    Abstract: A method for uniformly dispersing noble metal particles on a porous carrier by first mixing an alkoxide product of aluminum or silicon and a noble metal precursor together; then mixing a surfactant into the mixture; then mixing ammonia solution into the mixture to form a hydroxide of aluminum or silicon; then mixing a reducing agent into the mixture to convert the noble metal precursor into noble metal nanoparticles dispersed on the hydroxide; then separating the noble metal nanoparticles and the hydroxide from the mixture before calcining the hydroxide into an oxide of aluminum or silicon.
    Type: Grant
    Filed: March 13, 2003
    Date of Patent: January 31, 2006
    Assignees: General Motors Corporation, Chinese Academy of Sciences
