Enhanced photocatalytic activity over the Ag2O–g-C3N4 composite under visible light

An AgI@g-C3N4 hybrid core@shell structure: Stable and enhanced photocatalytic degradation

“…9). However, the peak relating to the Ag 3d spectrum has no significant shift and the result suggested that most of Ag + exist in the AgI@g-C 3 N 4 [28,34]. In the process of photocatalytic reaction, no obvious of metallic Ag was formed [36].…”

“…The peak at 398.2 eV is typically attributed to an N atom possessing two sp 2 -bonds with two carbon atoms (C N C). The two peaks at 399.3 and 400.5 eV could be assigned to tertiary nitrogen (N (C) 3 ) and amino functional groups with a hydrogen atom (N H) respectively [34].…”

Tetraethylorthosilicate induced preparation of mesoporous graphitic carbon nitride with improved visible light photocatalytic activity

“…3B. The peak at 398.9 eV was typically attributed to N atom sp 2 -bonded to two carbon atoms (C-N_C), two peaks at 399.8 and 401.1 eV could be assigned to tertiary nitrogen (N-(C) 3 ) and amino functional groups with a hydrogen atom (N-H) [28]. Elemental analysis indicated that the C/N ratios of mg-C 3 N 4 and bulk g-C 3 N 4 were 0.638 and 0.625, respectively.…”

Quantification of hydroxyl radicals on cementitious materials by fluorescence spectrophotometry as a method to assess the photocatalytic activity

“…This oxidative test has been proved to be an effective technique to identify the oxygen active species generated [45][46][47]. The results are given in Fig.…”
