Homogeneous catalysts, known for chemo-, regio- and enantioselectivity, have better contact with the reactants but the catalyst separation creates barriers. Heterogeneous systems enable better separation although at the cost of reduction in the availability of active sites. Because of the reduced size of nano-catalysts, surface is entirely available for the reaction and with the added benefit of its magnetic separation,1 this ‘quasi-homogeneous’ strategy can bridge both, homogeneous and heterogeneous catalysis;2,3 recent sustainable developments will be abridged. Graphitic carbon nitride (g-C3N4), a photoactive nitrogenous framework, facilitates reactions under the visible light;4 the immobilization of nanoparticles and the ensuing polymeric composites enable the development of useful photo-active heterogeneous catalysts in organic synthesis.5
