Abstract Mo 2 C MXene (Mo CT x ) is recognized as an excellent cocatalyst due to unique physicochemical properties and platinum‐like d‐band of active sites. However, sites with high‐density empty d‐orbitals exhibit strong Mo─H ads bonds during photocatalytic hydrogen evolution, leading easy adsorption ions from solution unfavorable desorption H To weaken the bond, a strategy oriented electron transfer Cu increase antibonding orbital occupancy hybrid orbitals implemented by introducing into interlayers form Cu‐Mo . The synthesized Ga CuCl via one‐step molten salt method combined TiO /TiO photocatalyst through ultrasound‐assisted approach. Hydrogen production tests reveal that exceptional performance (6446 µmol h −1 g , AQE = 18.3%) 8.4 fold higher than CF conventional etchant NH 4 F+HCl). Density functional theory (DFT) calculations characterization results corroborate increases in thereby weakening accelerating evolution rate This research offers valuable insights optimizing H‐adsorption capabilities at on materials.
