“…Among such carriers, the recently studied Fe-Cr-Al (FeCrAl alloy) sintered metal fibers (SMF) of porous sheets − formed by uniform microsized filaments present high porosities up to 80–90%. Since the original FeCrAl alloy SMFs do not have sufficient surface area (the SSA may reach 1–2 m 2 /g only), the application of this material as a carrier requires surface modification that may be achieved by special treatment, for instance, by high-temperature oxidation or acid treatment. − The enhancement of the specific surface area of the metallic carrier is beneficial for supporting active metals at high dispersion.…”

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.
