Highly efficient hydrogen generation from formic acid-sodium formate over monodisperse AgPd nanoparticles at room temperature

Monodisperse AgPd alloy nanoparticles are synthesized by co-reduction of silver nitrate and palladium acetylacetonate in 1-octadecene and oleic acid using tert-butylamine borane as the reducing agent at 60   °C. Thanks to the narrow size distribution of the AgPd alloy NPs and the synergistic effect with graphene, the as-synthesized Ag 74 Pd 26 /graphene exerts nearly 100% hydrogen selectivity and exceedingly high catalytic activity toward hydrogen generation from formic acid at room temperature, with the turnover frequency value of 572   h −1 .
