Novel Impregnated Support Combustion Synthesis of Stable Ni Catalysts for Hydrogen Production from Ethanol Reforming

Partial encapsulation, the surrounding of the metal by the support preventing agglomeration and carbon deposition while still allowing the reactants to reach the active surface, is demonstrated to prevent catalyst deactivation. Partially encapsulated Ni on SiO₂ prepared by ISCS under an inert atmosphere demonstrates no change after 100 h TOS.
