Abstract:
N-doped Graphene Quantum Dots (N-GQDs) as new carbon nanomaterials is designed and useful for designing metal oxide nanocomposites. Unlike previous reports, we focused on the facile method and green synthesis of N-GQDs from citric acid and ethylene diamine in simple conditions. ZnO based nanocomposites are veryinteresting for photocatalytic degradation for its advantagessuch as direct band gap, anisotropic growth, high electronmobility and simple controlling of its morphology and on the other hand, CuO nanostructures for their uniqueproperties have been found many applications in catalyst, sensor and ceramic feld. Till now many studies have been reported to investigate ZnO/CuO nanostructures and nano composite. ZnO/CuO@N-GQDs-PrNH2 nanoparticles have been used as an efficient and magnetically recoverable catalyst for the preparation trans-3-aryl-2-(4-bromobenzoyl) -2,3-dihydro-4H-furo[3,2-c]chromen-4-ones by multicomponent reaction in ethanol under reflux condition. Prepared furo[3,2-c]chromen and nano catalysts are characterized by X-ray diffraction analysis, 1H NMR, IR spectroscopy and single crystal analysis that the obtained furo[3,2-c]coumarins were the trans-isomers.
