Pd nano-size is 1.56+/-0.67nm in catalyst SiO2@Pd-PAMAM, so it has a superior performance in the hydrogenation reaction as catalyst. It can effectively catalyze olefins, alkynes, ketones, nitro etc in hydrogenation reaction with a conversion rate of 100%, and 100% selectivity, compared with the traditional Pa catalyst, the catalytic performance is doubled. In addition ,SiO2@ Pd-PAMAM catalyst can be repeated using five times to maintain the original catalytic efficiency, almost no exudation of Pd and mingled with reactants, and traditional Pa catalyst cycled three times will lose its catalytic properties.
