“…The tertiary [N-(C) 3 ] and secondary (-C-N=C) nitrogen in the aromatic structure are represented by the peak at 398.4 eV, the peak at 400.2 eV is attributed to an aliphatic C-N=N-C or residual C-NH 2 group, and the weak peak at 403.9 eV is associated with π-π* bonding [ 23 , 26 , 30 ]. The Ag 3d spectrum with two peaks detected at 367.8 and 373.8 eV is ascribed to the Ag 3d 5/2 and Ag 3d 3/2 binding energies of Ag + , respectively ( Figure 5 d), indicating the presence of Ag + in CNAC-10 [ 42 , 48 , 52 , 53 ]. Additionally, as for the deconvoluted O 1s high-resolution spectrum ( Figure 5 d), the center of the peak is located at about 531.1 eV, corresponding to the C-O bond in Ag 2 CO 3 [ 54 ].…”

The development of novel catalysts for degrading organic contaminants in water is a current hot topic in photocatalysis research for environmental protection. In this study, C3N5 nanosheet/Ag2CO3 nanocomposites (CNAC-X) were used as efficient photocatalysts for the visible-light-driven degradation of methylene blue (MB), and tetracycline hydrochloride (TC-HCl) was synthesized for the first time using a simple thermal oxidative exfoliation and in situ deposition method. Due to the synergistic effect of nanosheet structures, carbon defects, and Z-scheme heterojunctions, CNAC-10 exhibited the highest photocatalytic activity, with photodegradation efficiencies of 96.5% and 97.6% for MB (60 mg/L) and TC-HCl (50 mg/L) within 90 and 100 min, respectively. The radical trapping experiments showed that ·O2− and h+ played major roles in the photocatalytic effect of the CNAC-10 system. Furthermore, intermediates in the photodegradation of MB and TC-HCl were investigated to determine possible mineralization pathways. The results indicated that C3N5 nanosheet/Ag2CO3 photocatalysts prepared in this work could provide an effective reference for the treatment of organic wastewater.

“…It is accepted that the effluents (96% of occurrence) play an important role as pollutant sources to surface water [9]. Unfortunately, the pharmaceutical compounds and their metabolites, usually treated by WWTPs, reach the environment without undergoing any changes [10], since conventional treatment methods are unable to remove them.…”
