High Sintering-/Coke-Resistance Ni@SiO2/Al2O3/FeCrAl-fiber Catalyst for Dry Reforming of Methane: One-Step “Macro to Nano” Organization via Cross-Linking Molecules

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. Such catalyst is active, selective and stable for the strongly endothermic dry reforming of methane (DRM), as the result of enhancement of resistance to coke and Ni-sintering arised from the core-shell-like nanostructure. Notably, no sign of catalyst deactivation is observed with almost no carbon deposition even after 500 h testing at 800 oC and a gas hourly space velocity of 5000 mL g-1 h-1.
