Gold was deposited on ultrastable Y (USY) zeolite using a newly developed method: just mixing an aqueous solution of HAuCl4and zeolite at 353 K in which the NH4+cation reacted with the Cl−in HAuCl4. Treatment of the Au-loaded USY zeolite in the atmosphere of hydrogen resulted in the formation of Au0nanoclusters with 1.8 nm diameter at 773 K. The size of Au particle was dependent on the type of zeolite support, composition of gas atmosphere, and temperature of calcination, which was correlated with catalytic performance. This study demonstrated the potential use of zeolites with strong Brønsted acid character as gold supports.
