Nickel-induced morphology change of mesostructured alumina with enhanced catalytic activity for selective CO methanation

Abstract

Nickel-induced morphology change of mesostructured alumina with amorphous walls to bayerite tetrahedra when treated in water, and then to γ-alumina with worm-like mesopores topologically after it was calcined at 400 °C is reported. The catalytic activity for selective CO methanation increased significantly after this treatment.
