Palladium nanoparticles (1.88nm) uniformly dispersed on a porous N-doped “leavening” carbon (Pd/NHPC-AC) have been successfully developed, which can be served as a highly active and stable catalyst for the selective decomposition of formic acid under mild conditions. The Pd/NHPC-AC catalyst exhibits enhanced activity for H2 production (TOF=4115h−1 at 60°C) without CO in comparison with Pd/HPC-AC (without nitrogen doping) and Pd/AC under the same reaction conditions. The doping of nitrogen could prevent the Pd nanoparticles from aggregation and leaching from the support surface and therefore improving the reusability of the catalyst.
