Electron transfer enhancing the Mn(II)/Mn(III) cycle in MnO/CN towards catalytic ozonation of atrazine via a synergistic effect between MnO and CN

Da Wang et al.

Summary: In this study, a new type of hybrid material Mn-nCN, composed of manganese oxide (MnO) dispersed on carbon-nitrogen (CN) material, was fabricated as a catalyst for heterogeneous catalytic ozonation (HCO) and showed excellent catalytic performance in degrading refractory organic pollutants. The synergistic effects between MnO and CN, facilitated by the C-N-Mn and C-O-Mn bonds in the catalyst, overcome typical issues such as metal leaching, and promote redox reactions of Mn by promoting electron transfer from cation-pi reactions. The study also demonstrated the involvement of surface hydroxyl groups in ozone decomposition and reactive oxygen species (ROS) production.

Insight Into the CuOx Interacts with Oxygen Vacancies on the Surface of Black-TiO2 for NO Oxidation

Maorun Hu et al.

Summary: Designing non-precious catalysts with high active sites for optimized NO oxidation activity remains a challenge. A low-cost and high-active CuOx/black-TiO2 catalyst was prepared, showing a higher NO oxidation efficiency at 350 degrees C compared to CuOx/TiO2. Raman spectra and XPS analysis indicated strong interaction between CuOx and black-TiO2, leading to better reduction property and higher gas adsorption capacity in CuOx/black-TiO2.

Efficient degradation of trimethoprim by catalytic ozonation coupled with Mn/FeOx-functionalized ceramic membrane: Synergic catalytic effect and enhanced anti-fouling performance

Manman Li et al.

Summary: In this study, a modified flat microfiltration ceramic membrane (Mn-Fe-CM) was used to catalyze ozone (O-3) for the oxidative degradation of trimethoprim (TMP). The Mn-Fe-CM showed improved catalytic performance for O-3 compared to the conventional CM. The degradation and mineralization efficiencies of TMP were enhanced in the O-3/Mn-Fe-CM system. The proposed degradation mechanism involved hydroxylation, carbonylation, demethoxylation, and deamination. The O-3/Mn-Fe-CM system exhibited strong catalytic ozonation performance and good anti-membrane fouling ability, making it suitable for surface water treatment.

Study on the synergy effect of MnOx and support on catalytic ozonation of toluene

Yilin Dong et al.

Summary: MnOx has received widespread attention in low-temperature catalytic oxidation of VOCs, but the synergy effect of MnOx and support on the VOCs catalytic ozonation has been rarely studied. In this study, different MnOx/X materials were synthesized and it was found that the support greatly affects the catalytic oxidation activity. MnOx/MCM-41 exhibited the best catalytic activity, completely degrading O3 and VOCs at room temperature. Moreover, MnOx/MCM-41 showed strong water resistance and stability. The supply of loading sites and the improvement of interfacial electron transfer are the manifestations of the synergy between the support and MnOx in promoting the catalytic ozonation of VOCs.

Grey Fe-CeO2-σ for boosting photocatalytic ozonation of refractory pollutants: Roles of surface and bulk oxygen vacancies

Xixi Chen et al.

Summary: The surface and bulk oxygen vacancies in grey Fe doped CeO2-sigma can be tuned to affect light absorption, charge transfer, and catalytic activity, ultimately enhancing catalytic activity by producing more reactive oxygen species and accelerating electron transfer. Surface oxygen vacancies facilitate ozone adsorption, while bulk oxygen vacancies promote ozone dissociation into reactive surface oxygen.

Kinetic Modeling-Assisted Mechanistic Understanding of the Catalytic Ozonation Process Using Cu-Al Layered Double Hydroxides and Copper Oxide Catalysts

Yuting Yuan et al.

Summary: In this study, copper aluminum layered hydroxides and copper oxide were used as catalysts for heterogeneous catalytic ozonation, targeting the removal of oxalate and formate contaminants. The role of the catalyst in contaminant removal was elucidated, with Cu-Al LDHs facilitating slow decay of O-3 to form surface hydroxyl radicals, while CuO rapidly transforms O-3 into surface-located hydroxyl radicals and/or other oxidants. Futile consumption of surface-located oxidants via interaction with the catalyst surface was minimal for Cu-Al LDHs, but becomes significant with higher CuO dosages.
