Photocatalysis of Cr- and Fe-Doped CeO(2) Nanoparticles to Selective Oxidation of 5-Hydroxymethylfurfural

Oxygen vacancies (V(o)) present in CeO(2) nanoparticles (NPs) can effectively boost their photocatalytic activity under ultraviolet (UV) light. To improve photocatalytic performance, Cr- and Fe-doped CeO(2) NPs with increased V(o) were prepared using a simple method of doping Cr and Fe ions into CeO...

description Oxygen vacancies (V(o)) present in CeO(2) nanoparticles (NPs) can effectively boost their photocatalytic activity under ultraviolet (UV) light. To improve photocatalytic performance, Cr- and Fe-doped CeO(2) NPs with increased V(o) were prepared using a simple method of doping Cr and Fe ions into CeO(2) NPs, which was confirmed by an in-depth analysis of the structural and electronic changes. Through photocatalytic degradation (PCD) experiments with 5-hydroxymethylfurfural (HMF), we found that the PCD rates of the two doped CeO(2) NPs were faster than that of the CeO(2) NPs. In addition, the conversion of HMF to 2,5-furandicarboxylic acid (FDCA) using the doped CeO(2) NPs occurred only through the mechanism of the selective oxidation to 5-hydroxymethyl-2-furancarboxylic acid (HMFCA), exhibiting better efficiency than using CeO(2) NPs.
