Formation and Catalysis of Gold Nanoparticles Generated through the Physical Mixing of AuCl(PPh₃) and Oxides

Abstract

AuCl(PPh₃) was mixed with various kinds of inorganic supports with a mortar. Thermal treatment of the mixture resulted in the formation of gold nanoparticles, particularly when NaY zeolite and CeO₂ were employed as the supports for gold. Catalytic performance in the aerobic oxidation of benzyl alcohol was in good correlation with the degree of the dispersion of gold.

Key words

gold - nanoparticle - zeolite - alcohol - oxidation
