Abstract
In this study, we report the synthesis and characterization of biocompatible hyaluronic acid-stabilized copper nanoparticles (HA-CuNPs) and their catalytic evaluation in the oxidation of morin as a model compound. HA-CuNPs have been characterized by several state-of-the-art analytical techniques, such as FESEM, STEM, UV–Vis, DLS, zeta potential, FTIR and XRD analyses. The average particle size and surface zeta potential of HA-CuNPs were determined to be 35 nm and −28 mV, respectively. The catalytic activity of HA-CuNPs was investigated in the oxidative degradation of morin dye in the presence of H2O2. The kinetic data show that the oxidation process follows a pseudo-first-order reaction, and the rate constant is dependent on the concentrations of morin, H2O2, and HA-CuNPs. In addition, HA-CuNPs were employed for the selective oxidation of morin on four important synthetic dyes, i.e.,…
