Aqueous‐Phase Partial Oxidation of Methane over Pd−Fe/ZSM‐5 with O2 in the Presence of H2
Von Wiley-VCH zur Verfügung gestellt
Pd-Fe/ZSM-5 catalysts selectively oxidize CH4 to methane oxygenates (CH3OH, HCOOH, etc.) in water using in situ-generated H2O2. 0.28 %Pd–0.56 %Fe/ZSM-5 showed a stable catalytic performance in a continuous flow reactor.
The selective oxidation of methane into methane oxygenates such as CH3OH and HCOOH with O2 is a promising technology for direct methane conversion. This study successfully demonstrates the partial oxidation of methane over Pd−Fe/ZSM-5 catalysts in water, where H2O2 was generated in situ from H2 and O2. A low Pd content is essential for preventing agglomeration of Pd nanoparticles, and intimate contact between Pd and Fe species is beneficial for achieving high yields of methane oxygenates. This one-body catalyst showed better catalytic performance than that of previously reported ones, especially at low temperatures. 0.28 %Pd–0.56 %Fe/ZSM-5 exhibited a stable catalytic performance in a continuous flow reactor.Zum Volltext
