摘要：

A novel heterogeneous photoactive catalyst is developed by incorporating ruthenium over a new photoactive graphite carbon nitride (g-C3N4) support for efficient photocatalytic transfer hydrogenation of various carbonyl functional group compounds with different alcohols. A synthesized photoactive catalyst Ru-g-C3N4 exhibits good to excellent reactivity with a high turnover number (TON) under mild reaction conditions and under visible light. The physicochemical properties of the photocatalyst were analyzed by XRD, BET analysis, TGA, FT-IR, XPS, UV-visible, ICP-OES, TEM and SEM characterization techniques. The main significant features of the photoactive catalyst Ru-g-C3N4 are viz., it is easy to handle in visible light (LED lamp), does not require an external base, solvent free, non-toxic, environmentally friendly and proceeds under very mild reaction conditions. Furthermore, the solid photocatalyst Ru-g-C3N4 can be recycled efficiently and reused many times, without a major loss in reactivity.
