Nanocarbons in different structural dimensions (0–3D) for phenol adsorption and metal-free catalytic oxidation

Direct fabrication of lamellar self-supporting Co3O4/N/C peroxymonosulfate activation catalysts for effective aniline degradation

“…It was well known that Å OH and SO 4 ÀÅ radicals show different reaction rates with EtOH and TBA [71]. EtOH can capture both Å OH and SO 4 ÀÅ while TBA prefers capturing Å OH radicals rather than SO 4 ÀÅ radicals [72,73]. Therefore, the dominant radical species for aniline degradation could be well distinguished through adding EtOH or TBA into reaction solution.…”

Heterogeneous degradation of refractory pollutants by peroxymonosulfate activated by CoOx-doped ordered mesoporous carbon

“…Due to its high surface area, accessible mesopores and large pore volume, OMC had been applied in many areas such as adsorbents [32], catalysts and supports [33,34], and electrode materials [35]. Recently, 3D hexagonally-OMC (CMK-3) and cubically-OMC (CMK-8) were reported for PMS activation and their catalytic activity were much higher than CNTs and 2D graphene nanoplate [29,36]. As a good support, the high surface area of OMC could greatly increase the dispersity of cobalt species, and its instinct catalytic activity for PMS activation contribute to the removal of organic pollutants.…”

Hierarchically-structured Co–CuBi 2 O 4 and Cu–CuBi 2 O 4 for sulfanilamide removal via peroxymonosulfate activation

“…While these methods are effective, they are generally limited by the possibilities of secondary pollutant generation after treatment, huge capital cost for installation and tedious operating conditions. Advanced oxidation processes (AOP) based on the generation of reactive radicals (particularly sulfate radical, SO 4 •− ) from peroxymonosulfate (PMS) activation are increasingly being adopted as an effective treatment method to degrade recalcitrant organics in water [9][10][11][12]. The sulfate-radical-based AOP is effective over a wide range of pH and can be more effective than hydroxyl radical ( • OH) due to its better selectivity for electron transfer reaction.…”
