Photocatalytic performance of alkali metal doped graphitic carbon nitrides and Pd-alkali metal doped graphitic carbon nitride composites

A g‐C3N4/PANI S‐scheme heterojunction with face‐to‐face structure to improve the anticorrosion property on Q235 steel and enhanced mechanism study

“…The peaks at about 1600 and 1550 cm −1 were attributed to the CC stretching modes of quinone ring and benzene ring. The peak at 3210 cm −1 is regarded as the NH bond between amine and imine centers 43,44 . For the g‐C 3 N 4 , the peaks at 1250, 1325, 1420, and 1639 cm −1 attributed to the typical stretching patterns of C, N heterocycles.…”

“…The peak at 3210 cm À1 is regarded as the N H bond between amine and imine centers. 43,44 For the g-C 3 N 4 , the peaks at 1250, 1325, 1420, and 1639 cm À1 attributed to the typical stretching patterns of C, N heterocycles. In addition, the peak at 810 cm À1 was attributed to the breathing pattern of the s-triazine ring system, which is a unique structure of g-C 3 N 4 .…”

Sodium alkoxide-mediated g-C3N4 immobilized on a composite nanofibrous membrane for preferable photocatalytic activity

“…The above results have an agreement with the conclusion of alkali metal (Li + , Na + , K + ) doping modication. [50][51][52] Combined with the mechanism of alkali metal doping modied g-C 3 N 4 , the presence of sodium will increase the electron density of the carbon nitride plane, reduce the localization of electrons, and form an electron transport channel to facilitate the transport of carriers.…”

LaVO4 with alkali metal doping for enhanced photocatalytic water splitting

“…Thus, Na-doped g-C 3 N 4 is a promising substance that can be used to improve the photocatalytic performance of hydrogen production. 11 Diao et al used a seed-assisted hydrothermal method to grow rutile TiO 2 nanorod arrays on carbon cloth and doped them with K, Na, and Cl using a thermal diffusion method. The photocatalytic degradation results showed that the response of the alkali metal-doped TiO 2 array under visible light illumination was satisfactory.…”
