A glucose-assisted redox hydrothermal route to prepare a Mn-doped CeO₂ catalyst for the total catalytic oxidation of VOCs.

ABSTRACT: In this study, a novel glucose-assisted redox hydrothermal method has been presented to prepare an Mn-doped CeO₂ catalyst (denoted as Mn-CeO₂-R) for the first time. The obtained catalyst contains uniform nanoparticles with a small crystallite size, a large mesopore volume, and rich active surface oxygen species. Such features collectively contribute to improving the catalytic activity for the total catalytic oxidation of methanol (CH₃OH) and formaldehyde (HCHO). Interestingly, the large mesopore volume feature of the Mn-CeO₂-R samples could be considered an essential factor to eliminate the diffusion limit, favoring the total oxidation of toluene (C₇H₈) at high conversion. Therefore, the Mn-CeO₂-R catalyst outperf
