Organic-inorganic composite of g-C3N4–SrTiO3:Rh photocatalyst for improved H2 evolution under visible light irradiation

Enhanced photocatalytic activity of BaTiO3@g-C3N4 for the degradation of methyl orange under simulated sunlight irradiation

“…Generally, most of the photogenerated electrons and holes recombine rapidly and only a few of them participate in redox reactions. It is noted that g-C 3 N 4 has a CB potential of À1.12 eV and a VB potential of 1.58 V [26,27], which are negative to the CB and VB potentials of BaTiO 3 , respectively. This indicates that the BaTiO 3 @g-C 3 N 4 composite has well-matched overlapping band-structures, as schematically shown in Fig.…”

“…Furthermore, it can be readily prepared from inexpensive precursors via a simple heat treatment process [22][23][24][25]. Particularly, g-C 3 N 4 has been frequently used as an ideal narrow-bandgap semiconductor to combine with wide-bandgap photocatalysts to form heterostructured composites with enhanced photocatalytic performance [26][27][28][29][30]. By comparing the energy-band potentials of g-C 3 N 4 with those of BaTiO 3 , it is found that the two photocatalysts exhibit well-matched overlapping band-structures, which indicates that they are suitable to construct heterostructures with high photocatalytic activity.…”

Textural and electronic structure engineering of carbon nitride via doping with π-deficient aromatic pyridine ring for improving photocatalytic activity

“…Various strategies, such as microstructure regulations [5][6][7][8][9][10], heterojunction [11][12][13][14][15][16][17], doping [18][19][20][21][22], and copolymerization [23][24][25][26][27][28][29][30] have been exploited to improve the photocatalytic activity and adjust selectivity photocatalytic activity of CN. Among those strategies, copolymerization that another organic monomer is mixed with the precursor during the preparation of CN has been regarded as an efficient route, not only for modulating the electronic and band structure of CN via control its -conjugated aromatic system, but also for creating surface dyadic heterostructures to promote splitting and separation of the separated electrons and holes at the materials surface, thus leading to an enhancement in its photocatalytic activity.…”
