Acid-tolerant intermetallic cobalt–nickel silicides as noble metal-like catalysts for selective hydrogenation of phthalic anhydride to phthalide

Abstract

Intermetallic Co–Ni silicide catalyst embedded in a carbon matrix with a unique synergistic effect exhibits excellent activity, selectivity, and acid corrosion resistance in hydrogenation of phthalic anhydride to phthalide, which matches noble metal catalysts.
