MXenes with crinkled 3D structure possess high conductivity, and stability for application in electrocatalysis. Herein, we assess promising Ti3C2 as durable and active support candidates in Pt-loaded catalytic systems to drive the Hydrogen Evolution Reaction (HER) in proton exchange membrane fuel cells (PEMFC). The 3D MXene materials were obtained through several treatment and carefully characterized through SEM, TEM, ICP, XPS, and XRD analyses. Specific electrochemical properties have drawn due to distinct termination groups on the surface of Ti3C2. However, the effect of these surface functional groups, which may play a crucial role to optimize the interaction with loaded Pt nanoparticles, has not been fully investigated to date. In this work, we direct our attention to the effect of these surface functional groups on the resulting interactions with Pt to improve the electrocatalytic activity and durability of Pt-loaded Ti3C2 materials toward HER in PEMFC. |
