Ag 3 PO 4 /α-Fe 2 O 3 composites were synthesized by a solvothermal method and a stepwise electrostatic adsorption method. Under visible light irradiation, the acceleration of charge transfer in Ag 3 PO 4 /α-Fe 2 O 3 inhibits the recombination of photogenerated charges, thereby ameliorating the photocatalytic properties of Ag 3 PO 4 and α-Fe 2 O 3 and promoting the yields of radical oxygen species. Ag 3 PO 4 /α-Fe 2 O 3 can be used for effective sterilization, and the antibacterial efficiency reaches up to 99.51 and 99.91% for Staphylococcus aureus and Escherichia coli, respectively, within 15 min visible light irradiation. This work brings new insights into the rapid disinfection of environments with pathogenic microorganisms using α-Fe 2 O 3 -based photocatalyst materials.

“…The XRD patterns in Figure a reveal the typical graphitelike structure of bulk g-C 3 N 4 in the angular range of 10–80°. Notably, two distinct characteristic peaks of g-C 3 N 4 are present at 27.8 and 13°; these peaks can be indexed to the hexagonal phase of polymeric carbon nitride (JCPDS 87-1526) . The characteristic peak at 13° belongs to the characteristic (100) in-plane structural packing motif, and the other pronounced peak at 27.8°, which can be indexed as (002), represents the interlayer stacking reflection of aromatic systems.…”

In this study, a solar/chlorine/graphitic carbon nitride (g-C 3 N 4 ) system for the highly efficient degradation of carbamazepine (CBZ) was constructed, and the degradation mechanism of CBZ in this system was elucidated. The removal rate of CBZ by g-C 3 N 4 combined with solar/chlorine was as high as 97.8%, which was more than twice that of the solar/chlorine combined system (43.8%). Electron spin resonance analysis revealed that the hydroxyl radicals (HO • ) in the solar/chlorine/g-C 3 N 4 system were remarkably less than that in the solar/chlorine photocatalytic system, wherein HO • was the dominant participant. However, the former system had higher efficiency than the latter. Scavenging tests confirmed the existence of a synergistic effect between solar/chlorine and g-C 3 N 4 in CBZ degradation, and ground-state atomic oxygen (O( 3 P)) played a more important role than HO • in the solar/chlorine/g-C 3 N 4 system. A novel O 3 -related pathway of CBZ degradation was proposed on the basis of the determination of intermediates. The intermediates detected via liquid chromatography quadrupole time of flight mass spectrometry (LC/Q-TOF-MS)/MS analysis indicated that O 3 attacked the double bond of CBZ via the Criegee mechanism and produced intermediates with two new aldehydes. This study not only improved the knowledge of the effects of O( 3 P) and the O( 3 P)-related degradation mechanism of organic pollutants but also provided a reminder that O( 3 P) might be overlooked in the photocatalytic processes, especially in processes that occur in the presence of dissolved oxygen or oxygen-containing anions.

“…However, the PL spectra intensity of the obtained samples are weakened in the sequence of GCN > GF > GV > GFV nanocomposite. Generally, having a lesser PL intensity is signifying that the more outstanding photo-excited charge separation ability with lower recombination and electron binding rate, also the prolonged lifetimes [56]. This is because the cocatalyst of V 2 O 5 on the GF composite surface which significantly promotes the photo-excited charge transfers could efficiently hinder the recombination rate.…”
