Construction of molecularly doped and cyano defects co-modified graphitic carbon nitride for the efficient photocatalytic degradation of tetracycline hydrochloride

Abstract

Structural modulation of graphitic carbon nitride (g-C3N4) is regarded as an effective strategy to boost its photocatalytic behavior. Herein, we have synthesized 4,6-Dimethyl-2-hydroxypyrimidine-doped and cyano-defects co-modified graphitic carbon nitride (HDMP-CD-g-C3N4)...

Benzene Bridged Carbon Nitride for Efficient Photocatalytic Hydrogen Evolution

“…Lin et al synthesized g-C3N4 doped with 4,6-dimethyl-2-hydroxypyrimidine (HDMP) through in-situ copolymerization. HDMP doping reduces the band gap, thus promoting the light absorption of g-C3N4, and accelerates the transfer of photogenerated electrons as an electron acceptor [29]. Leonard Heyman et al prepared triazinyl doped g-C3N4 molecule by electrochemically polymerizing 2,4,6-triaminopyrimidine (TAP) and melamine molecular, which improved the photocatalytic performance [30].…”

Enhanced visible-light-driven RhB removal with a Mo–Ni bimetallic sulfide/g-C3N4 nanosheet Schottky junction

“…Graphite carbon nitride (g-C 3 N 4 ), as a well-known efficient visible-light-driven (VLD) photocatalyst, exhibits prominent application prospects in environmental purification and remediation, especially in the degradation of organic pollutants. [1][2][3] Notably, g-C 3 N 4 is set apart from various VLD photocatalysts owing to its low cost, high chemical stability, and suitable potential structure. [4][5][6] Unfortunately, bulk g-C 3 N 4 usually suffers problems of insufficient active sites and a high recombination rate of photogenerated electron-hole pairs, which greatly limits its development and practical application.…”
