a H2-TPD profiles of Pd/MCMOS, Ru/MCMOS, the physically mixed catalyst (Pd/MCMOS + Ru/MCMOS) and Ru/Pd/MCMOS. b H2-TPR profiles of Pd/MCMOS, RuOx/MCMOS, the mixture of Pd/MCMOS and RuOx/MCMOS, and RuOx/Pd/MCMOS. c Schematic illustration for neighboring metal-assisted hydrogenation over Ru/Pd/MCMOS. d The rate constant of NB (k1) and AN transformation (k2) in the sequential hydrogenation reaction over Ru/Pd/MCMOS with different Ru/Pd ratios. e The rate constant of NB (k1) and AN transformation (k2) in the sequential hydrogenation reaction over the physically mixed catalysts with different Ru/Pd ratios. f The relationship between the Ru/Pd ratio and the CA production rate in the sequential hydrogenation reaction.
