Title: L-Phenylalanine-Templated Platinum Catalyst with Enhanced Performance for Oxygen Reduction Reaction

Journal Article · · ACS Applied Materials and Interfaces

Pt-based materials are the most efficient catalysts for the oxygen reduction reaction (ORR) in proton exchange membrane fuel cells. However, fabrication of active and stable Pt catalysts still remains challenging. In this work, Pt-L-phenylalanine (Pt-LPHE) films, with highly dispersed Pt nanoparticles (NPs) featuring predominately (111) facets, have been prepared via a room temperature electron reduction (RTER) method. Loading Pt-LPHE onto carbon support produces a novel nanomaterial (Pt-AL/C), resulting in a simultaneous loading of highly dispersed Pt NPs and N-doping. Density functional theory (DFT) calculations demonstrate that the N dopants stabilize the Pt NPs and reduce the *O/*OH binding energies on the Pt NPs. As a result, the Pt-AL/C nanomaterial shows significantly enhanced ORR activity and stability over commercial Pt/C after 10,000-cycle stability tests. This work provides a novel eco-friendly and energy neutral approach for preparing metal NPs with controllable structures and sizes.
