Insights into the photocatalytic activation persulfate by visible light over ReS2/MIL-88B(Fe) for highly efficient degradation of ibuprofen: Combination of experimental and theoretical study

Photothermal Localization in an Optofluidic Microreactor for Rapid Pretreatment toward Online Pollutant Analysis

“…Meanwhile, potassium persulfate was activated under heat, MnO 2 , and UV irradiation, and its contribution rates were 28.43, 37.44, and 14.57%, respectively. The above three methods are also very classic PDS activation methods. − And we speculate that the reaction of MnO 2 with potassium persulfate leads to the change of its element valence content. At the same time, the ratio of the contact area between MnO 2 and the liquid phase to the liquid phase volume in the reaction chamber reached 20 000 m 2 /m 3 , which may also lead to the highest digestion efficiency of MnO 2 -activated potassium persulfate .…”

Degradation of tetracycline by persulfate oxidation promoted by iron-modified biochar

“…Although a large amount of iron oxides would have been formed at the same time, the reason for the observed phenomenon may be the destruction of oxygen-containing functional groups during high-temperature carbonization. 8 The high-resolution XPS spectrum of Fe 2p in Fe@BC could be deconvoluted into three characteristic peaks, of which the peak at 711.3 eV was assigned to the 2p3/2 orbital of Fe 3+ .…”

“…Recently, carbon nanotubes, carbon fiber, and graphene have been considered promising supporting matrices for PMS activation. [7][8][9] However, the high cost and complex preparation process limit its practical application. As a green material, carbon has been widely studied due to its large specific surface area, easy availability, and low cost.…”

The composing effect of bismuth on titania hollow microspheres for their visible-light photocatalytic activity

“…Therefore, it is necessary to adopt a green water treatment technology similar to photocatalysis, which is efficient, non-toxic, has low energy consumption, and has no secondary pollution. [11][12][13][14][15][16] However, pristine TiO 2 could only utilize small ultraviolet illumination of solar energy owing to its wide band gap (3.2 eV), 17 which impedes its practical application. To solve that deficiency, plenty of expansions have been made to achieve visible-light photocatalysts.…”
