Surface sensitization of g-C3N4/TiO2via Pd/Rb2O co-catalysts: accelerating water splitting reaction for green fuel production in the absence of organic sacrificial agents

“…54 After the formation of the composite (g-C 3 N 4 /TiO 2 ) and co-catalyst (Pd and Rb 2 O) loading, the band edge has shown a slight red-shift in comparison to rutile TiO 2 . 55 The most active photocatalyst (Pd–Rb 2 O@g-C 3 N 4 /TiO 2 ) showed a narrow E g at 2.95 eV which is less than the E g of TiO 2 while greater than the of E g of g-C 3 N 4 , which happened due to the formation of a heterojunction and loading of co-catalysts. 56,57 The palladium metal nanoparticles provided the excited SPR e − to the redox centre (synthesized heterostructure) as shown in Fig.…”

A review on the advancements of graphitic carbon nitride-based photoelectrodes for photoelectrochemical water splitting

“…181 Synthesis of TNAs by electrochemical anodization on a titanium substrate and the facile thermal treatment using suitable substrates for the formation of g-C 3 N 4 /TiO 2 heterojunction is one of the most adopted strategies. [182][183][184] A diagram of the charge transfer mechanism of the g-C 3 N 4 /TNTA heterojunction electrode and the photocurrent density of different photoanodes is given in Fig. 6.…”

Recent advances on g-C3N4-based Z-scheme photocatalysts for organic pollutant removal

“…Water pollution has attracted growing interest because of the rapid industrial development and expanding population. [1][2][3][4][5][6] The exploration and development of advanced technologies, such as adsorption, [7][8][9][10] electrocatalysis, 11,12 and photocatalysis [13][14][15][16][17][18][19] (especially visible-light-responsive photocatalysis), [20][21][22][23][24] are very promising for overcoming these issues. Among them, the most promising strategy is photocatalysis because of its unique advantage in simply using inexhaustible solar energy to organic pollution removal.…”
