MXenes are highly conductive materials with a high surface area, offering potential as promising catalyst supports in proton exchange membrane fuel cells (PEMFCs), a technology recognized for sustainable energy conversion. This study centers on a comparative analysis of various platinum (Pt) loadings uniformly distributed across MXene sheets to enhance catalytic performance. The synthesized materials were comprehensively characterized using X-ray diffraction (XRD), X-Ray Photoelectron Spectrscopy, scanning electron microscopy (SEM) and Raman spectroscopy to investigate their structural attributes and morphology and functional groups, providing insights into their stability and interaction with Pt particles. Electrochemical tests were conducted in rotating disc electrode (RDE) and half-cell setup to assess the efficiency of the catalysts in oxygen reduction reaction (ORR), a crucial step in PEMFC performance due to its role in limiting cell output. Results reveal that Pt particles on MXenes not only function effectively as ORR electrocatalysts but also improve reaction kinetics, positioning MXene-supported Pt catalysts as a promising alternative for PEMFC applications.
