▎ 摘 要
A facile approach has been developed for the synthesis of highly porous Pd nanostructures (PPd NSs) and their graphene hybrid (RG-PPd NSs). The PPd NSs are well-dispersed on the graphene support and retain their unique morphology. The RG-PPd NS modified electrode shows high sensitivity towards H2O2 without the usage of a redox mediator/enzyme.
