The electro-deposition method is a novel method for metal catalyst preparation. Platinum supported on an anodic alumite film using the electro-deposition method was applied as a catalyst for the catalytic combustion of VOCs. The effect of the Support time oil the catalyst preparation was investigated if this work. The results showed that the short-time electro-deposition method was favorable for the preparation of noble metal catalysts, because it could provide high dispersion and high metal surface area. The catalysts developed using the short-time electro-deposition method also express good catalytic activity in the catalytic combustion reactions of VOCs, even with low metal loading.
