The effects of palladium addition and the reduction methods on Au/TiO2 were investigated. Pd was loaded on TiO2 firstly by incipient-wetness impregnation, Au was then loaded by deposition-precipitation method. The nominal load-ings of Au and Pd were 1 wt % and 0.01 wt%. The bimetallic catalysts were reduced by heating at 453 K, by flowing H
