摘要

•Pd particles ranging from single sites to nanoparticles were prepared and thoroughly characterized.•Direct synthesis of H2O2 over Pd/HAp catalysts showed remarkable size effects.•H2O2 selectivity of 94% over a Pd (dpd: 1.4nm) catalyst was observed.•The structure of active sites could be tailored simply by tuning Pd particle size.
