METHOD FOR MAKING MONODISPERSED NOBLE METAL NANOPARTICLES SUPPORTED ON OXIDE SUBSTRATES |
摘要 |
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. |
