Facile recoverable and reusable macroscopic alumina supported Ni-based catalyst for efficient hydrogen production

A γ-NA5 catalyst in the form of pellet was first to be reported and was pioneering in gasification to accelerate the production of syngas through biomass (palm empty fruit brunch) conversion. The synthesised γ-NA5 pellet possesses a high surface area of 212.32 m2g−1, which renders more active sites...
