Growing ZnIn2S4 nanosheets on FeWO4 flowers with p-n heterojunction structure for efficient photocatalytic H2 production

Tailored modifications of the electronic properties of g-C3N4/C2N-h2D nanoribbons by first-principles calculations

“…Alternatively, there is an overlap in the charge densities of CBM and VBM, indicating that g-C 3 N 4 /C 2 N-h2D nanoribbons favor electron-hole pair recombination. 44,45 This is very important for optoelectronics, microelectronics, and thermoelectric devices.…”

0D/2D Co0.85Se/TiO2 p–n heterojunction for enhanced photocatalytic H2 evolution

“…Under light illumination, the electrons on the CB of Co 0.85 Se migrate to that of TiO 2 , and the holes on the VB of TiO 2 can transfer to Co 0.85 Se via a p-n heterojunction. [66][67][68] The electrons from the CB of TiO 2 transfer to the surface of the catalyst and participate in the reduction of H 2 O to produce H 2 , and the h + at the VB of Co 0.85 Se is consumed by TEOA. The formation of the Co 0.85 Se/TiO 2 p-n heterostructure is not only beneficial for the utilization of solar light but also promotes carrier separation and transfer, leading to excellent photocatalytic activity.…”

Two dimensional twin T-graphene: monolayer for visible-light photocatalytic water splitting and bulk for anode material of magnesium batteries

“…For an excellent photocatalyst, the ability of harvesting sunlight, particularly visible and ultraviolet light, to give rise to electronhole pairs is crucial to water splitting. [37][38][39][40] To determine the optical absorption coefficient of the TTG, we have calculated its optical absorption spectrums that are polarized in X-direction and Z-direction of TTG, as shown in Fig. 3(d).…”
