Abstract

According to the different point of zero charge (PZC) of MoO₃ and carbon black (XC72R), an efficient method for preparing highly dispersed carbon-supported Pd/Mo bimetallic nanoparticles is described. The charge enhanced dry impregnation (CEDI) technique is developed for the preparation of Pd/Mo/C electrocatalysts by selectively driving the [Pd(NH₃)₄]²⁺ cations onto MoO₃ phase instead of carbon support. The CEDI method could minimize the migration of Pd away from the MoO₃ phase to carbon support during reduction up to 400°C. Oxygen reduction measurements by linear sweep voltammetry indicate the carbon-supported Pd/Mo catalyst prepared by the CEDI method has better catalytic activity than that prepared with the dry impregnation method as the CEDI method gives strong interactions between Pd and Mo.
