Decoration of graphene oxide as a cocatalyst on Bi doped g-C3N4 photoanode for efficient solar water splitting

Copper–Azolate Framework Coated on g-C3N4 Nanosheets as a Core–Shell Heterojunction and Decorated with a Ni(OH)2 Cocatalyst for Efficient Photoelectrochemical Water Splitting

“…The photovoltage shows the latent ability of the g-C 3 N 4 @CuAF/Ni­(OH) 2 electrode for photoelectrocatalytic water splitting. The further ability of the photoanode leads to reducing the onset potential, which is in good agreement with LSV results . The amount of negative shift of the Fermi level under light irradiation determines the OCP value of the photoanode in the light.…”

“…In the presence of g-C 3 N 4 , the photogenerated electrons do not apparently recombine with holes and are easily transferred with the aid of the Ni­(OH) 2 cocatalyst. The Ni­(OH) 2 cocatalyst improves the separation and transfer of the photogenerated charge carriers through producing the reaction active sites on the surface of the photoanode by interface junctions formed between g-C 3 N 4 @CuAF and Ni­(OH) 2 . , The performance of the g-C 3 N 4 @CuAF/Ni­(OH) 2 photoanode was compared with the most important reports that used MOFs in photoelectrochemical water splitting (Table ). Because several conditions and materials are used in water splitting, we selected works that are very similar to the present work.…”

“…The further ability of the photoanode leads to reducing the onset potential, which is in good agreement with LSV results. 41 The amount of negative shift of the Fermi level under light irradiation determines the OCP value of the photoanode in the light. The open-circuit photovoltage indicates the amount of band bending compared to that in the dark.…”

Recent progress on the use of graphene-based nanomaterials in perovskite solar cells

“…[70][71][72][73] Among these compounds, GBNs found a special place due to their unique properties including excellent electrical conductivity, EC, (7 × 10 7 to 1 × 10 8 S m −1 ), high thermal conductivity, TC (∼5000 W m −1 K −1 ), large theoretical specic surface area (2630 m 2 g −1 ), high carrier mobility (200 000 cm 2 V −1 s −1 ), high Young's modulus (∼1 TPa), and high mechanical strength (130 GPa). 66,[74][75][76][77][78][79][80][81] Also, GBNs increases the exibility of these cells. Due to the unique properties of GBNs, they have been used in numerous elds and practical applications, [82][83][84] in addition to PSCs, including in freshwater production by solar desalination, [85][86][87][88] degradation of pollutants, [89][90][91][92][93] oil/water separation, [94][95][96] and in medicine as antibacterial, 97-100 antiviral, 101 and anticancer agents, 102 biosensors, 103,104 and fuel cells 105 (see Fig.…”
