Catalytic oxidation of formaldehyde over Pt/Fe2O3 catalysts prepared by different method

- The preparation method could affect structure and properties of iron oxide supports and then further influence the activities of supported Pt catalysts.
- The catalyst prepared by colloid deposition method (Pt/Fe2O3-CD) exhibits high catalytic activity for the low-temperature oxidation of HCHO.
- Suitable interaction between Pt nanoparticles and iron oxide support play a crucial role in the oxygen activation at ambient temperature.
