Abstract

Solar energy has been proposed as the most attractive alternative energy source for the development of clean and renewable energy. Heterogeneous photo catalysis offers the capability to directly harvest, convert, and store solar energy in the form of sustainable organic fuels and platform chemicals. In such context, semiconductor photo catalysis has recently emerged as a promising technology for the generation of clean energy and for the application of solar energy in catalysis. Recently g-C₃N₄ is a polymer n-type semiconductor possessing unique electronic, optical, and physiochemical properties, which underpin its use in electronics, catalysis, and energy production/storage. Carbon nitride has attracted the attention of researchers because of its unique and interesting physicochemical properties viz., efficiency of operation under visible light, semiconductor properties (band gap of ~2.7 eV), high stability, nontoxicity, metal free organo catalyst, environmentally benign photo catalysts and simple fabrication from cheap raw materials without any additive. Recently, Prof Yoel Sasson; our research group demonstrated g-C₃N₄ based photo catalysis with enormous possibilities. Few of them are; we describe for the first time a pressure free, mild photochemical protocol for selective reduction of olefin and nitro compounds using a non-hazardous, abundant, and eco-friendly H₂O–Mg pair as a H₂ donor in the presence of a Pd-g-C₃N₄ photo catalyst at RT. The new reaction system is a more expedient and greener protocol compared to earlier studies. In another approach, a novel heterogeneous photoactive catalyst is developed by incorporating ruthenium over a new photoactive g-C₃N₄ support for efficient photocatalytic transfer hydrogenation with 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. In my present postdoc (RCPTM), we are exploring the single atom based g-C₃N₄ heterogeneous catalysis.
