Catalytic combustion of volatile organic compounds (VOCs) benefits from a low oxidation temperature due to less energy consumption. It is widely applied in the industry. Platinum catalysts supported on alumite film have been developed successfully in our group and have been applied in reactors for VOC catalytic combustion. In this work, a novel platinum catalyst was developed on an extremely thin alumite film, which was treated with etching technology before the anodic oxidation. The activity of the developed catalysts were evaluated with the catalytic combustion reaction of VOCs and the results indicate that the catalyst prepared on the extremely thin alumite film has almost the same activity as the catalyst supported on the conventional alumite film, although the platinum on the extremely thin alumite film is about 40% of the amount on the conventional alumite film. Moreover, the catalyst experiences good endurance towards the VOC catalyst combustion reaction. The platinum loading of the new catalyst is very low and the anodization time for the support is very short; hence, the manufacturing cost of the catalyst can be cut down about 60%. The developed catalyst was also applied in a VOC catalyst combustion reactor, which experiences good activity towards VOC combustion.
