Efficient reduction-oxidation coupling degradation of nitroaromatic compounds in continuous flow processes

Nitroaromatic compounds (NACs) with electron-withdrawing -NO2 groups are typical refractory pollutants. Here the authors designed the LaFe0.95Cu0.05O3@carbon fiber cloth (LFCO@CFC) to realize efficient reduction-oxidation coupling degradation of NACs with lower cost and higher durability.

Regulating nonradicals generation through peroxymonosulfate activation via localized dipole to enhance wastewater biodegradability

A Co-doped ZnO catalyst is developed to break charge symmetry at active sites, promoting the activation of peroxymonosulfate to generate nonradical species for efficient removal of electron-rich pollutants in complex water environments.

Long-range interactions driving neighboring Fe–N₄ sites in Fenton-like reactions for sustainable water decontamination

Non-metallic functionalized species in single-atom catalysts potentially contribute to catalytic performance. Herein, the authors report a long range interaction induced by intrinsic carbon defects to enhance the Fenton-like reactivity and stability of adjacent single-atom sites.

Dynamic active-site induced by host-guest interactions boost the Fenton-like reaction for organic wastewater treatment

Uncovering the dynamic evolution of active sites in the working conditions is crucial to realizing increased activity and enhanced stability of catalyst in Fenton-like activation. Herein, the authors capture the dynamic changes in the unit cell of Co/La-SrTiO3 catalyst during the exemplary peroxymonosulfate activation process.

Pauling-type adsorption of O₂ induced electrocatalytic singlet oxygen production on N–CuO for organic pollutants degradation

Side-on configuration of O₂ on the catalysts conventionally leads to reduction of O₂ to water. Here, the authors propose a nitrogen doping strategy with Pauling-type adsorption of O₂ for selective electrocatalytic singlet oxygen production.
