Highly active Ru-g-C₃N₄ photocatalyst for visible light assisted selective hydrogen transfer reaction using hydrazine at room temperature

The present study describes the highly efficient heterogeneous photoactive catalyst Ru-g-C₃N₄ screened for selective transfer hydrogenation of nitroarenes and olefins. Photoactive catalyst Ru-g-C₃N₄ exhibits excellent reactivity in visible light under very mild reaction conditions via using hydrazine hydrate as a source of hydrogen with high turnover number. The easily separable heterogeneous photoactive Ru-g-C₃N₄ catalyst is straightforward to handle in visible light (LED lamp), non-toxic, environmentally friendly and at the same time eliminates the use of high pressure hydrogenation reactors without the need for external sources of energy.
