dc.description.abstract | As phenol represents as the most typical persistent organic pollutants in wastewater, SO4 center dot--involved chemical oxidation techniques using monopersulfate (MPS) have been regarded as a promising method to eliminate phenol. Since Co3O4 is the benchmark heterogeneous catalyst for activating MPS, it is highly critical to investigate shape-varied Co3O4 catalysts with well-defined crystal planes for activating MPS to degrade phenol. Thus, the aim of this study is to elucidate how different Co3O4 catalysts with various well-defined planes would influence catalytic activities for MPS activation. Specifically, three Co3O4 nanocrystals are fabricated: nanoplate (NP), nanobundle (NB), and nanocube (NC) with different dominant exposed facets of {112}, {110}, and {100}, respectively. As the facets of {112} and {110} consist of more abundant Co2+/Co3+, Co3O4-NP and Co3O4-NB exhibit noticeably higher catalytic activities then Co3O4-NC for activating MPS to degrade phenol. Nevertheless, since Co3O4-NP shows a much higher surface area than Co3O4-NB, Co3O4-NP could exhibit a relatively high catalytic activity in comparison to Co3O4-NB. In addition, Co3O4-NP also exhibits much faster degradation kinetics with a rate constant of 0.061 min(-1) at 30 degrees C, and more resistance towards pH variation, with much stable reaction stoichiometric efficiencies (RSE) ranging from 0.034 to 0.039 at pH = 3 similar to 9, than the other two Co3O4 nanocrystals, making Co3O4-NP with the {112} facet a more outstanding Co3O4 for activating MPS to degrade phenol. | - |
