Effect of desilication on the catalytic activity of Fe-FER for direct, selective, partial oxidation of methane
Journal of Catalysis(2023)
摘要
•NaOH treatment enhances CH3O· groups migration from iron to silicon sites.•Diffusion and desorption of products on Fe-FER are promoted following alkaline treatment.•Stability of active oxygen species on Fe-FER can be controlled by NaOH treatment.
