Abstract Atomic clusters exhibit superior performance in heterogeneous catalysis due to their unique electronic states and highly exposed active surfaces. Nevertheless, significant challenges persist achieving the precise efficient synthesis of atomic while preventing undesirable formation coexisting species, particularly nanoparticles. Herein, a one‐step situ phase transition engineering strategy is reported for platinum by vapor deposition on Ti 3 C 2 Cl MXene TiC interface (Pt‐MXene/TiC) molten salt, where Pt can be acquired over slight amount contents (0.298 wt.%). The strongly polarized salt induces desired confinement atomic‐scale clusters. construction interfaces enhances local electric field accelerates electron transfer between substrate. As result, Pt‐MXene/TiC‐950 exhibits an exceptional increase mass activity turnover frequency (TOF) hydrogen evolution reaction (HER) at 49.4 46.7 folds 10% commercial Pt/C. Further theoretical calculations elucidate that species possess moderate d‐band center, which enables optimized selectivity intermediates adsorption HER process. This work provides some guidelines leveraging heterostructure enhance precision efficiency
