The preparation of Au-Pd catalysts involves various techniques, including:
1. Co-Deposition: This technique involves the simultaneous deposition of gold and palladium onto a support material, such as activated carbon or alumina. This method ensures uniform distribution and intimate contact between the two metals.
2. Impregnation: In this approach, solutions containing gold and palladium precursors are impregnated onto the support material. Subsequent reduction treatments help in the formation of bimetallic nanoparticles.
3. Sol-Gel Method: This method involves the formation of a gel from a colloidal solution containing the metal precursors. The gel is then dried and calcined to obtain the desired Au-Pd catalyst.
