Si-Im/HSO4(1-methyl-3-(3-(trimethoxysilyl) propyl) imidazolium hydrogen sulphate functionalized Copper oxide nanoparticles(CuO NPs )as a novel supporting ionic liquid was prepared and characterized by FT-IR spectroscopy, FE-SEM, XRD, TGA, and EDX techniques. It was used as a recyclable catalyst for the one-pot, three-component synthesis of 1, 4- dihydro Pyrano [2, 3-c] pyrazoles derivatives. The results showed that the […]
Green synthesis of cupric oxide nanoparticles (CuO NPs) has been promoted as an environmentally-friendly, cost-effective and high yield method. The CuO NPs have been synthesized by reducing copper sulphate using an aqueous flower extract of Clitoria ternatea. The UV-visible peak observed at 251 nm confirmed the formation of CuO NPs. The optical bandgap energy value […]
