摘要：

The continuous catalytic oxidation of methane to methanol on a Cu-KFI zeolite using water-O-2 mixture as the oxidant is reported. A high methanol space-time yield of 880.3 mmol mol(Cu)(-1) h(-1) with 83% selectivity is achieved at 450 degrees C. Isotopic labelling experiments show that both H2O and O-2 provide the oxygen source in this catalytic methane-to-methanol conversion reaction.
