Abstract MXenes, a novel family of 2D materials, are energy materials that have gained considerable attention, particularly for their catalytic applications in emerging areas such as CO 2 and N hydrogenation. Herein, the first time, it is shown surface reducibility Ti 3 C T x MXene can be tuned by doping, which induces change properties supported Co nanoparticles. Pristine Co–Ti favors production during hydrogenation, whereas CH 4 favored when subjected to simple doping. X‐ray photoelectron spectroscopy transmission electron microscopy (TEM) reveal rutile TiO nanoparticles appear on support upon interact strongly with This interaction alters at interface nanoparticles, shifting product selectivity from . study successfully showcases practical strategy, based chemistry modulation regulating distribution
