The ability to generate valuable products through oxidation makes it one of the most pivotal industrial processes. While organic oxidants have traditionally been the focus in converting alcohols into carbonyl compounds, inorganic oxidants have been relatively underutilized. In this study, we delve into the influence of Potassium periodate (KIO4) in an acidic environment on the oxidation of selected alcohols, comparing its performance with that of catalyst silver nanoparticles prepared from two distinct plant sources: Madhuca longifolia flowers and Ziziphus jujuba leaves. The reactions were intentionally conducted under conditions that adhere to first-order kinetics. At regular intervals throughout the reaction, iodometric measurements were employed to monitor the progress of the reaction. It was noted that the oxidation rate exhibited a proportional increase corresponding to the concentration of alcohol for all the alcohols examined, while it decreased with an increasing concentration of the oxidant. In contrast, when AgNP catalysts were employed in conjunction with KIO4, significantly higher rate constants were achieved compared to using KIO4 alone. This research underscores the potential of silver nanoparticles prepared from plant sources as effective catalysts for alcohol oxidation, offering promising avenues for the development of more efficient and sustainable oxidation processes in the industry.
