Visible LED photocatalysis combined with ultrafiltration driven by metal-free oxygen-doped graphitic carbon nitride for sulfamethazine degradation

Direct Z-scheme P–TiO2/g-C3N4 heterojunction for the photocatalytic degradation of sulfa antibiotics

“…In path III, the molecular structure of pyrimidine is rearranged to form P7, and finally, the C–N bond is broken to form P8. 64–66…”

“…In path III, the molecular structure of pyrimidine is rearranged to form P7, and nally, the C-N bond is broken to form P8. [64][65][66] 3.5.2 Degradation pathway for sulfadiazine (SD). Fig.…”

Heterogeneous visible-light promoted dehydrogenative [4 + 2] annulation of benzothioamides and alkynes under aerobic conditions

“…12 In addition, electron paramagnetic resonance (EPR) spectra showed the characteristic peaks of DMPO-O 2 ˙ − (DMPO, 5,5-dimethyl-1-pyrroline N -oxide) (Fig. S15†), 13 indicating the formation of the superoxide radical under visible-light irradiation. Combination of these experimental results suggested the involvement of radical intermediates and single electron transfer in the photochemical reaction.…”

Oxygen-doped Carbon Nitride Nanocages with Efficient Photon-to-Electron Conversion for Selective Oxidation of Xylose/Xylan to Yield Xylonic Acid

“…However, in general, pure CN suffered from a low photon-to-electron conversion rate. Currently, many efforts (e.g., elements/molecules doping [5][6] , semiconductors/conductors loading [7][8][9] , carbon materials/ dyes sensitization [10] , nanostructure regulation [11][12] ) have been devoted to address this issue. For example, the regulation of one/two/three-dimensional nanostructures for CN can effectively increase its specific surface area, which not only improves the selective adsorption of reactants but also facilitates the utilization rate of visible light [13] .…”
