Abstract
Copper nanoparticles (CuNPs) have generated a great deal of interest in recent years, especially in catalysis are one of the promising materials in the advancement of copper-based technological applications. We synthesized copper nanoparticles through chemical reduction method using L- ascorbic acid at two different quantities and their spherical and flower like morphologies revealed by FE-SEM. This study also augmented with the catalytic conversion of 4-nitrobenzaldehyde to 4-nitrobenzoic acid using stated copper nanoparticles as a heterogeneous catalyst. Kinetic studies on the conversion of 4-nitrobenzaldehyde to 4-nitrobenzoic acid with time intervals of 30 min up to 180 min revealed the time required for the completion of the reaction. 1H NMR corroborated the product so obtained by the use of CuNPs as a catalyst, and ATR-IR analysis. A simple method of melting point exploited here to confirm the final product is a value-added. Thus, this simple analytical tool can boost the morale of researchers with limited resources in graduate and post-graduate laboratories.
