Electron rich P doped g-C3N4 for photodegradation of 2,4-dichlorophenoxyacetic acid under visible light by improving oxygen adsorption: Performance and catalytic mechanism

Transition of Schottky to Ohmic Contact via P Doping Promotes Efficient H2 Evolution of g-C3N4

“…This peak is indicative of the characteristic P–N bond (P–C bond low ∼1 to 2 eV), , indicating the most probable substitution of P for C within the triazine ring. In addition, 31 P solid-state MAS NMR of PCN (Figure S7b) shows an obvious signal from 20 to −40 ppm, corresponding to the fact that the C atoms in the bay carbon (position 1) and corner carbon (position 2) positions of the CN framework were replaced by P atoms, further proving the successful P doping, which is consistent with XPS results.…”

“…Meanwhile, the DOS diagram shows that the VB maximum (VBM) of CN primarily originates from N, while the CB minimum (CBM) of CN is jointly composed of C and N, aligning with previous research. 40,49 In PCN, P contributes to both VBM and CBM. It is worth noting that the midgap states created by the hybridization of C, N, and P can be observed at energy levels lower than the CBM of PCN.…”

A sulfur-doped alga-like g-C3N4 photocatalyst for enhanced photocatalytic and antimicrobial properties

“…In addition, elemental doping can effectively adjust the energy band structure of g-C 3 N 4 , improve the electron–hole separation, and significantly increase the carrier lifetime. The doping of non-metallic elements such as S, 28,29 B 30,31 and P, 32,33 can provide g-C 3 N 4 with higher photoelectric performance and photocatalytic activity. g-C 3 N 4 can also be composited with other materials to construct heterojunction materials, such as g-C 3 N 4 /TiO 2 34–37 and g-C 3 N 4 /ZnO, 38–40 which can improve the photogenerated charge separation and maintain a high redox capacity of the catalysts.…”
