Review and Perspectives of Carbon-Supported Platinum-Based Catalysts for Proton Exchange Membrane Fuel Cells

Energy & Fuels, Journal Year: 2023, Volume and Issue: 37(16), P. 11532 - 11566

Published: Aug. 3, 2023

The proton exchange membrane fuel cell (PEMFC) is a fast growing next-generation energy conversion technology, which has broad application prospects in electric vehicles, such as portable power supplies, fixed and the military industry. development of PEMFCs attracted much attention due to their high efficiency, good low-temperature startup performance, no pollution, noise, other advantages. However, cathodic oxygen reduction reaction (ORR) kinetics cells slow. It therefore necessary that we use large number carbon-supported platinum (Pt)-based catalysts order speed up reaction. As result, current problems cost low durability Pt-based have become major reason for limiting successful commercialization cells. To meet requirements catalytic activity stability catalysts, this review summarizes research progress methods optimizing performance PEMFCs. In addition, highlights improving terms particle size, exposure highly active crystal surfaces, control Pt morphology, preparation Pt–M alloys well some support characteristics technologies. Furthermore, direction main challenges they will face practical applications are also proposed review. summary, optimized using above show great potential ORR. With continuous improvement characterization technologies, market prospects.

Local Oxidation Induced Amorphization of 1.5‐nm‐Thick Pt–Ru Nanowires Enables Superactive and CO‐Tolerant Hydrogen Oxidation in Alkaline Media

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(43)

Published: June 19, 2023

Abstract Low‐dimensional amorphous metallic nanomaterials provide great possibility for creating high‐performance electrocatalysts owing to their conspicuous reacting merits derived from the flexible coordination structures, but remain extremely challenging in synthesis. Herein, this work reports a facile synthesis of carbon‐loaded 1.5‐nm‐thick Pt–Ru nanowires (NWs) through local oxidation induced amorphization process. During annealing premade crystalline NWs/C air, local‐oxidation oxyphilic Ru generates abundant random Ru–O bonds and disturbs order bimetallic lattices. The as‐prepared Pt 53 47 (a‐Pt ) exhibits an high activity (13.7 A mg −1 at 25 mV overpotential) excellent CO‐tolerance alkaline hydrogen reaction (HOR) electrocatalysis, drastically outperforming counterpart commercial benchmarks. Mechanism studies indicate effects as well rich disordered “Pt–Ru–O” and/or “Pt–O–Ru” atomic heterojunctions can weaken *H binding energy inversely strengthen *OH adsorption, thus promoting HOR kinetics. More uniquely, small interatomic spaces bond nets present H 2 /*H‐selected permeability, which spatially obstruct relatively larger CO molecules poison internal catalytic sites during HOR. CO‐shielded enriched surface jointly upgrade a‐Pt catalysts.
