Sintering improved porous palladium nanoparticle membrane self-assembled at water/pentanol interface for nonenzymatic glucose sensor

Palladium membrane with porous structure was synthesized through self-assembly of Pd nanoparticles (NPs) at the interface between water and pentanol under ambient condition. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images revealed that the as-synthesized Pd membrane presented nano-network structure with very high porosity. The porous Pd membrane exhibited well electrocatalytic activity and high sensitivity toward nonenzymatic glucose oxidation. It might have a promising outlook in the applications for glucose sensor due to its facility in preparation and well properties.
