Abstract

Carbon monoxide (CO) is extremely poisonous to the Pt catalyst resulting in the available reaction surface reduction and fuel cell performance degradation. Therefore, the reform of natural gas or other hydrocarbons is avoided to be used as the CO is inevitable. CO-tolerant catalysts are required to overcome this bottleneck. Herein, MXene (Ti₃C₂T_x) and carbon nanotube (CNT) hybrid materials are used as the catalytic support to load Pt nanoparticles (NPs) to achieve the anode catalyst for proton-exchange-membrane fuel cell (PEMFC). The Pt/Ti₃C₂T_x-CNT catalyst performs higher hydrogen oxidation reaction (HOR) activities and stability compared with the Pt/C catalysts, and the peak power density of PEMFC based on the Pt/Ti₃C₂T_x-CNT catalyst achieves 0.86 W cm⁻² with H₂/air and 1.6 W cm⁻² with H₂/O₂. Furthermore, the Pt/Ti₃C₂T_x-CNT catalyst exhibits superior electrocatalyst activity and remarkable CO-tolerant performance, which could be attributed to the metal-support interactions between Pt nanoparticles and Ti₃C₂T_x-CNT hybrid supports.
