Herein, a high-performance Pt-Rh alloy cocatalyst was successfully loaded onto commercial TiO<sub>2</sub> (P25) using a solvothermal method. The optimized Pt-Rh alloy-supported P25 catalyst (Pt-Rh/P25) exhibited exceptional photocatalytic hydrogen evolution activity, achieving a remarkable production rate of 23391.0 μmol·g<sup>–1</sup>·h<sup>–1</sup> under simulated solar irradiation. This performance represents significant enhancements of 2.14-, 3.60-, and 377.2-fold compared to the Pt/P25, Rh/P25, and bare P25 catalysts, respectively, outperforming most reported TiO<sub>2</sub>-based photocatalytic systems to date. The remarkable photocatalytic performance of Pt-Rh/P25 was attributed to its improved light absorption capacity and enhanced utilization efficiency of photogenerated carriers. Theoretical calculation indicated that Pt-Rh/P25 exhibited optimized *H adsorption free energy, which significantly promoted photocatalytic hydrogen production kinetics.
