Accelerated photocatalytic degradation of iohexol over Co3O4/g-C3N4/Bi2O2CO3 of p-n/n-n dual heterojunction under simulated sunlight by persulfate

Anchoring Co3O4 nanoparticles on conjugated polyimide ultrathin nanosheets: construction of a Z-scheme nano-heterostructure for enhanced photocatalytic performance

“…4c, respectively. 38 It can be clearly seen that the binding energies of the Co 2p peaks associated with the 3.0CO/SPI composite have decreased and moved to 778.7, 779.5, 794.1, and 795.1 eV, respectively. In contrast, the N 1s binding energies of 3.0CO/SPI composite shifted 0.2, 0.3, and 0.4 eV to higher binding energy compared with SPI.…”

Towards synergistic combination of biochar/ultrasonic persulfate enhancing removal of natural humic acids from water

“…6c, DMPO-X with an intensity ratio of 1:2:1:2:1:2:1 was detected in the biochar/persulfate/ultrasonic treatment system, which is an oxidized derivative produced by the oxidation of DMPO. Some studies have also found such phenomenon in the biochar/ persulfate systems [42][43][44]. They attributed the production of DMPO-X to the reaction between DPMO and •OH and SO 4 − • generated from the activation of persulfate.…”

Design and engineering of graphene nanostructures as independent solar-driven photocatalysts for emerging applications in the field of energy and environment

“…7(b) shows the time course of the photocatalytic H 2 production shown with the highest rate as observed for 80% EtOH compared to that in in H 2 O. Very recently, Xiang et al 119 studied the photocatalytic H 2 production and degradation of RhB dye under visible light. The porous P-doped graphitic carbon nitride (g-C 3 N 4 ) and B-doped graphene nanomaterials were used for that purpose.…”
