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, its excellent properties verified in experiments. different pathways oxygen activation by revealed characterization experiments calculations. species effectually reduced the dissociation energy barrier H2O adsorbed on surface, surface hydroxyl group promoted O2 formation •O2- under light humid conditions. introduction more vacancies, which served as adsorption sites gaseous O2. Meanwhile, electron transfer accelerated contributed to rapid production •OH light. synergistic effect successfully achieved simultaneous improvements activity, stability, water resistance Co3O4/TiO2. Furthermore, catalyst was applied degradation multicomponent VOCs, reaction path analyzed test intermediates, along with an investigation interaction among types VOCs. This study provided a new idea optimization polymetallic catalysts analysis paths
