Fibrous spherical ni-m/zsm-5(m:mg, ca, ta, ga) catalysts for methane dry reforming:the interplay between surface acidity-basicity and coking resistance

A highly active and robust fibrous spherical ZSM-5-supported nickel catalyst with different promoters (Mg, Ca, Ta, Ga) have been synthesised by microemulsion method for dry reforming of methane (DRM). The structural framework provided by the unique fibrous spherical ZSM-5 aided confinement of Ni par...
