| Research Abstract |
Bimetallic nanoparticles consisting of gold and palladium were successfully immobilized on titanium dioxide surface by unique sonochemical reduction method. The photocatalytic activities depended on the inner structure of the immobilized bimetallic particles, in other words, the distribution of the constituent metals in each particle, even with same components. Alloying two or more metals and designing their inner structure were found to provide superior catalyst to the constituent metals.
