The optimum reaction parameters for CO oxidation in the presence and absence of H₂ have been investigated by photoreduction method to enhance the catalytic activity and selectivity of CO₂ for CO preferential oxidation (PROX) in H₂-rich stream in detail. X-ray photoelectron spectroscoopy (XPS) results showed that part oxygen vacancies produced on the surface of photoreduced catalysts, which maybe the activity site for the chemisorbed H. Therefore, a possible bi-function reaction mechanism for CO preferential oxidation over the photoreduced Pt/TiO₂ catalyst has been proposed.
- CO preferential oxidation,
- Pt catalyst,
- Photoreduction,
- Impregnation
