Abstract

A perforated N-doped monoclinic ZnWO4 nanorod photocatalyst for excellent hydrogen production via water splitting under sunlight.

Efficient photocathodic protection enabled by a multi-dimensional quaternary hybrid superstructure

“…Meanwhile, the width of the VB is increased due to an extended mixing of orbitals, indicating the enhancement of the density of electrons [110]. As can be seen in Fig.…”

A Review on the Synthesis and Characterization of Metal Organic Frameworks for Photocatalytic Water Purification

“…Titanates (BaTiO3, SrTiO3 or La2Ti2O7) [42][43][44] Tungstates (Bi2WO6 or ZnWO4) [45,46] Metalates [AxByOz] (such as BiVO4) [47,48] Non-metal semiconductors g-C3N4, graphene [49][50][51] Multicomponent materials Bi2S3/Bi2O3/Bi2O2CO3 Bi2O2CO3/Bi2O4 [52][53][54] BiVO4/Bi2O2CO3 g-C3N4-heterojunctions [50] Graphene-heterojunctions [55] Simultaneously, during this last two decades, another type of materials has received special attention photocatalysis, regarding the broad range of possibilities that the interaction between metal clusters and organic linkers may present. This is the case of metal organic frameworks (MOFs), whose crystalline structure provides a robust and well-defined network and also a high development of the surface area [56].…”

Thin‐Layered Photocatalysts

“…Through doping nonmetal element, such as oxygen, carbon, nitrogen, sulfur, phosphorus, boron, and so on, the bandgap of the thin‐layered materials can be narrowed with an extended light harvesting region, which can not only improve the photocatalytic ability, but also provide opportunities for constructing metal‐free photocatalytic systems. [ 149–153 ] Taking h‐BN as an example, the theoretical calculation results determine that the h‐BN is not suitable for being applied as the photocatalyst, which is attributed to their wide bandgap (4.56 eV). Utilizing a simple pyrolysis method, different amount of carbon element can be successfully introduced into the lattice of the h‐BN, indicated by the X‐rays diffraction (XRD), Fourier transform infrared spectroscopy (FT‐IR), 13 C solid‐state nuclear magnetic resonance (NMR), XPS, Raman, and the electron energy loss spectroscopy results, and generate the thin‐layered h‐BCN with a thickness of about 4 nm.…”
