Description
In this study, we report on the hydrothermal synthesis of MnOx-anchored carbon spheres as an effective catalyst. A new method is employed to prepare carbon spheres from cellulose. Using a solvent-free process, the prepared catalyst is used to convert o-cresol to salicylaldehyde. Methods including XRD, Raman spectroscopy, FE-SEM, EDS mapping, and HR-TEM are used to examine the structural and morphological characteristics of the catalyst. It is confirmed from the BET analysis that doping with MnOx increases the surface area of the carbon spheres. At standard atmospheric pressure, the conversion of o-cresol to salicylaldehyde is highly selective due to the enhanced surface area and active sites of MnOx-doped carbon spheres. Under atmospheric pressure, the MnOx/CS catalysts show excellent efficiency, yielding 96% salicylaldehyde in under 1 h. This study underscores the feasibility of using MnOx-doped carbon spheres as a robust catalyst for the controlled oxidation of o-cresol. The results show that the catalyst has a great deal of activity and effectiveness, as well as being cheap and reusable, which greatly increases its potential for real-world catalytic applications. 2025 Wiley-VCH GmbH.
