Zinc oxide nanoparticles immobilized on a graphitic carbon nitride (ZnS NPs/g-C3N4) nanocomposite were applied as an organometallic recyclable catalyst in the synthesis of coumarin-chalcone hybrids through the Claisen-Schmidt condensation of different aromatic aldehydes and 3-acetyl coumarin. The nanocomposite increased the rate and facility of the aforementioned reaction and represented a strong influence in the green synthesis of different coumarin-chalcone derivatives. The nanocatalyst has been characterized by N-2 adsorption-desorption, Fourier transform infrared spectroscopy, scanning electronic microscopy, powder X-ray diffraction and energy dispersive spectroscopy. Some advantages of this novel and sustainable approach are high yields of coumarin-chalcone compounds, short reaction times, environmentally benign, recoverability of ZnS NPs/g-C3N4 and reusability without important loss of catalytic activity.
