HI decomposition over active carbon supported binary Ni–Pd catalysts prepared by electroless plating

Abstract

A series of binary Ni–Pd catalysts supported on active carbon was prepared by electroless plating method. For comparison, active carbon supported monometallic Pd and Ni catalysts were also prepared by liquid-phase reduction. Among the Pd, Ni and binary Ni–Pd catalysts, the catalyst of 1%Ni–1%Pd/C showed the best catalytic performance for the decomposition of HI. Furthermore, characterizations by BET and XRD revealed that the binary Ni–Pd catalyst had the higher stability in specific surface area and structure than monometallic Pd catalyst during HI decomposition.
