Au-Pd alloy catalyst with high performance for hydrogen generation from formic acid-formate solution at nearly 0 degrees C

摘要

By reduction of mixed noble metal precursors in aqueous phase under ice-water bath conditions, well dispersed Au-Pd alloy nanoparticles supported on carbon black were facilely prepared. The catalyst exhibited high activity and selectivity at nearly 0 degrees C, with an initial turnover frequency (TOF) up to 635 h(-1). At room temperature the initial TOF of the catalyst reached 1075 h(-1), which is rather high compared with those reported in the literature.
