New way of preparation of nanoporous electrocatalysts

Our doctoral student Xianxian Xie and coworkes published recently paper "A Facile Way for Acquisition of a Nanoporous Pt–C Catalyst for Oxygen Reduction Reaction" in Advaced Materials Intefraces the concept of preferential leaching of cerium oxide on ternary Pt–C–CeO₂ compound in order to develop a cost-effective oxyhen reduction reaction catalyst for proton exchange membrane fuel cells. During an activation electrochemical treatment, CeO₂ was leached from the compound, leaving behind a porous Pt–C matrix, which exhibited significant improvement in ORR activity in both half-cell and single-cell configurations.
