The synthesis, characterization, and photo/catalytic activity in transfer hydrogenation reaction (TH) of g-C3N4/TiO2 supported Ru@g-C3N4/TiO2 nanocatalysts whose surfaces were modified with different ratios of Ru nanoparticles were reported. The structure, composition, and morphology of the as-prepared nanophotocatalyst were elucidated by XRD, UV-DR, FT-IR, SEM-EDX, HR-TEM, BET, and XPS analysis. The catalytic system worked well for the transfer hydrogenation with significant activity and selectivity. Ru@g-C3N4/TiO2 catalyst was used in the transfer hydrogenation reactions of acetophenone under aerobic conditions in 0.1 M isoPrOH solution, in open air and at room temperature, showing high efficiency and high conversion (up to 99%). These results proposed that the improved activity predominantly benefits from the synergistic effects of Ru nanoparticles on g-C3N4/TiO2 nanocomposite that cause efficient separation and excited charge carriers and redox capability of the nanocatalyst. Therefore, tuning of band gap of g-C3N4 makes a significant advancement in the photo/catalytic transfer hydrogenation reactions.
