Two-dimensional CdS/SnS2 heterostructure: A highly direct efficient Z-scheme water splitting photocatalyst

A desired water splitting photocatalyst should not only possess suitable bandgap and band edge position, but also host the spontaneous progress for overall water splitting without the aid of any...

Intrinsic defect engineered Janus MoSSe sheet as a promising photocatalyst for water splitting

The Janus MoSSe sheet has aroused significant attention due to its band edge position and intrinsic dipole moment, making it a strong candidate for water splitting photocatalysis.

Charge, adsorption, water stability and bandgap tuning of an anionic Cd(ii) porphyrinic metal–organic framework

By changing the occupancies of the metal ions and counterions, the tuning of the framework charge, band-edge position and bandgap of a novel Cd(ii) porphyrinic MOF 1 was achieved.

Impact of the anodization time on the photocatalytic activity of TiO2 nanotubes

Titanium oxide nanotubes (TNTs) were anodically grown in ethylene glycol electrolyte. The influence of the anodization time on their physicochemical and photoelectrochemical properties was evaluated. Concomitant with the anodization time, the NT length, fluorine content, and capacitance of the space charge region increased, affecting the opto-electronic properties (bandgap, bathochromic shift, band-edge position) and surface hydrophilicity of TiO2 NTs. These properties are at the origin of the photocatalytic activity (PCA), as proved with the photooxidation of methylene blue.

Effects of crystal structure and composition on the photocatalytic performance of Ta–O–N functional materials

In Ta–O–N functional materials, the interaction between atomic core and valence electronic states, and the overlapping between valence electronic states mainly influence the band gap and the band edge position. According to the requirements, Ta3N5 and TaON are suitable candidate materials for efficient photocatalyst.

ZnO/MoX2 (X = S, Se) composites used for visible light photocatalysis

The ZnO/MoS2 (ZnO/MoSe2) heterostructures with the strain of –2% (+2%) have suitable bandgap and band edge position for hydrogen production via visible light photocatalytic water splitting.

Electronic properties of red and black phosphorous and their potential application as photocatalysts

The promising potential of monolayerrPandbPas photocatalysts was identified, due to their suitable band gap, appropriate band edge position, higher mobility and separation efficiency of charge carriers, and strong response to visible light.
