Abstract
Copper oxide (CuO) nanoparticles are prepared by the hydrothermal method which is used as a heterogeneous catalyst to synthesize 3-(2-chlorophenyl)-2,4-Pentadione. The energy band gap of HOMO-LUMO of CuO NPs is calculated using a UV-vis study which is found to be 1.96 eV. The crystalline development in the CuO NPs is investigated by X-ray peak broadening of the characteristic peak (111) of the XRD-diffractogram using Scherrer’s formula, the average particle size (D), and d-spacing of the CuO NPs are evaluated 15.04 nm and 2.761 A°, respectively. The catalytic activity of CuO NPs is higher than the normal bulk form of CuO in the synthesis of3-(2-chlorophenyl)-2,4-Pentadione. The use of CuO NPs catalyst minimizes the reaction time. The percent yields of the product obtained by the same quantity and concentration of 5 mmol of CuO NPs and bulk CuO are 78 and 45, respectively.
