This study focuses on the preparation and characterization of porous N-doped carbon derived from chitosan, which serves as a solid support for earth-abundant transition metal oxides. Fe2O3, CoO, NiO, and CuO nanoparticles are loaded onto the support and used as catalysts for the oxidation of primary alcohols using peroxydisulfate or peroxymonosulfate. Quenching tests suggest the presence of a significant contribution from a non-radical oxidation process.
The selective oxidation of alcohols aiming at the formation of aldehydes and esters is an essential reaction for the fine chemical industry. However, the classical processes to obtain aldehydes present many limitations, such as waste generation, low selectivity, or high cost. Herein, we address the production and characterization of porous N-doped carbon derived from chitosan. This solid was used as the support for earth-abundant transition metal oxides such as Fe2O3, CoO, NiO, or CuO nanoparticles. These materials were used as catalysts for the oxidation of primary alcohols by activating peroxydisulfate or peroxymonosulfate. Quenching tests were performed and a considerable contribution of a non-radical oxidation process was indicated.
