摘要: FePO4/SiO2,as an inexpensive and widely used material, was firstly employed for the oxidative bromination of methane, which showed effective and stable performance at 570℃, namely, 49% methane conversion and 95% total selectivity for CH3Br/CO(CH3Br:CO ≈1)were obtained on a single pass. The products could be directly used as a feedstock for the manufacture of acetic acid. 57Fe Mossbauer spectroscopic studies revealed that the FePO4 components of the fresh catalyst transformed quickly into stable active species during the induction period, and the active components of the stable catalyst have been found to consist of near-equimolar α-Fe3(P2O7)2 and Fe2P2O7.
