Sumario:[Image: see text] Efficient structured catalysts of partial methane oxidation into synthesis gas were obtained by electrochemical modification of the surface of sintered FeCrAl alloy fibers in an ionic liquid BMIM-NTf(2) with further introduction of platinum nanoparticles. It was shown that etching and electrochemical modification of sintered FeCrAl alloy fibers result in a decrease of the surface aluminum content. With an increase of the reaction temperature to 900 °C, the methane conversion reaches 90% and the selectivity to CO increases significantly to achieve 98%. The catalysts with a Pt loading of 1 × 10(–4) wt % demonstrate high activity and selectivity as well as TOF in synthesis gas production by the CH(4) + O(2) reaction at 850–900 °C. To trace the composition and structure evolution of the catalysts, XRD and SEM methods were used.
