Al-27 and Si-29 NMR studies of alumina and amorphous silica-alumina supported NiW(Mo) HDS catalysts
Surface reaction of NiW species with silanol groups of amorphous silica alumina support and a partial regeneration of silanols and disruption of the monolayer due to sulfidation were found by Si-29 MAS-NMR.
