  "abstract": "Platinum (Pt) remains the benchmark catalyst for the hydrogen evolution reaction (HER), yet its performance in alkaline media is limited by sluggish water dissociation kinetics. Herein, we report a facile polyol synthesis of Pt nanoparticles supported on delaminated Mo₂CTz MXene labeled d-Mo2CTz and comparison is made with a reference Pt/carbon (C) catalyst at similar metal loadings. While structural analyses reveal comparable particle sizes, enabling isolation of support effects, XPS and electrochemical measurements evidence metal support interaction in Pt/d-Mo₂CTz, leading to modified hydrogen adsorption behavior. As a result, Pt/d-Mo₂CTz exhibits enhanced HER activity in alkaline media, requiring an overpotential as low as 48 mV at − 10 mA cm− 2 to be compared to 70 mV for Pt/C. This enhanced activity is attributed to two different phenomena: Pt ensures hydrogen recombination and the MXene support promotes water adsorption, activation, and hydroxide removal thanks to its hydrophilic/oxophilic properties. These findings highlight the active role of MXene supports in tuning Pt electrocatalysis properties and provide new design strategies for efficient alkaline electrolyzers.",
