Boosting the Photothermal Oxidation of Multicomponent VOCs in Humid Conditions: Synergistic Mechanism of Mn and K in Different Oxygen Activation Pathways
University of Shanghai for Science and Technology · Liaocheng University
Abstract
The complexity of actual industrial emissions has brought significant challenges for volatile organic compounds (VOCs) purification. Herein, Mn and K atoms were incorporated into Co3O4/TiO2 through theoretical study, and its excellent properties were verified in experiments. The different pathways of oxygen activation by Mn and K were revealed by characterization experiments and theoretical calculations. Mn species effectually reduced the dissociation energy barrier of H2O adsorbed on the surface, and the surface hydroxyl group promoted the dissociation of O2 and the formation of •O2– under light and humid conditions. The introduction of K promoted the formation of more oxygen vacancies, which served as…
