In-situ reduction synthesis of nano-sized Cu2O particles modifying g-C3N4 for enhanced photocatalytic hydrogen production

Plasmon-enhanced photocatalytic properties of nano Ag@AgBr on single-crystalline octahedral Cu2O (1 1 1) microcrystals composite photocatalyst

“…The diffuse reflectance spectrum of as-prepared Cu 2 O has a broad absorption in the visible range with a characteristic peak at 485 nm, and two subpeaks at 335 and 421 nm that may be attributed to free excitons [27]. Clearly, the absorption onset of pure Cu 2 O was at approximately 650 nm, which agreed well with a bandgap of 1.9 eV, which is in accord with the reported value [28]. It has also been reported that for Cu 2 O NPs with size of about 2-3 nm, the band gap might increase to 2.40 eV due to quantum size effect [29,30].…”

Novel CuCo2O4/graphitic carbon nitride nanohybrids: Highly effective catalysts for reducing CO generation and fire hazards of thermoplastic polyurethane nanocomposites

“…The g-C 3 N 4 and its various derivatives have been widely applied in the fields of catalysts, lithium ion storage, and optoelectronic devices, etc. [21][22][23][24][25][26]. Owing to incomplete polycondensation, this material is endowed with a small amount of -NH and/or -NH 2 groups on terminal edges [27,28].…”

g-C3N4/Ag3PO4 composites with synergistic effect for increased photocatalytic activity under the visible light irradiation

“…The g-C 3 N 4 catalyst is endowed with a high thermal stability and chemical stability because of its tris-triazine ring structure [20]. In addition, g-C 3 N 4 has appropriate band positions and band gap energy (2.7 eV), which brings that g-C 3 N 4 is easily excited by the visible light to produce electrons and holes [21]. However, the pure g-C 3 N 4 has low photocatalytic performance due to the rapid recombination of photoinduced electrons and holes [15].…”
