Development of a Pt/TiO2 catalyst on an anodic alumite film for catalytic decomposition of formaldehyde at room temperature

A Pt/TiO2 catalyst was prepared on an anodic alumite film and employed in the catalytic decomposition of formaldehyde at room temperature. The results show that the catalyst exhibits good activity toward the decomposition of formaldehyde at room temperature when the anodic alumite film is treated in hot water. Moreover, in accordance with the process requirements, the developed catalyst can be formed into various shapes such as a mesh, plate, fin, serrate etc., because aluminum can be formed into any shapes.
