Abstract

A thin-felt, microfibrous-structured Ni@SiO₂/Al₂O₃/FeCrAl-fiber catalyst was fabricated by one-step, top-down macro-micro-nano organization with the aid of cross-linking molecules followed by a calcination treatment. This catalyst is active, selective and stable for the strongly endothermic dry reforming of methane (DRM), as the result of its enhanced resistance to coke and Ni sintering arising from its core-shell-like nanostructure. Notably, no sign of catalyst deactivation is observed, with almost no carbon deposition even after 500 h testing at 800 °C and a gas hourly space velocity of 5000 mL g^-1 h^-1.
