Abstract Metal/MXene‐based materials show broad prospects in energy conversation through the strong metal‐support interaction (SMSI). However, difficulty and harshness of synthesis heavily limit their further application. Herein, using Lewis acidic molten salt to etch MAX as a precursor MXene, more convenient safer strategy is designed situ construct MXene‐supported CoIr nanoalloy (CoIr/MXene) catalyst Ti─O─M bond. The special layered structure oxygen‐containing functional group MXene regulate SMSI upon nanoalloys. Moreover, contact angle Raman test results exhibit good interface hydrophilicity enhancing water adsorption on interfaces, accelerating mass transfer process. As result, CoIr/MXene shows high hydrogen evolution reaction (HER) performance, which only needs overpotentials 34 50 mV drive current density 10 mA cm −2 alkaline media, respectively, with excellent stability. Especially, possesses 6 times higher HER activity (4.297 A mg Ir −1 ) than commercial Pt/C catalysts (0.686 Pt at potential mV, indicating larger active site intrinsic for CoIr/MXene. This work expands application assist etching provides new insight development metal/MXene‐based catalysts.
