Construction of a 2D nanoplate-like MoS 2 /Bi 2 WO 6 heterojunction with enhanced visible-light photocatalytic activities

A highly active Z-scheme SnS/Zn2SnO4 photocatalyst fabricated for methylene blue degradation

“…The decrease in bandgap owes to the lattice dislocation at the interface of Zn 2 SnO 4 and SnS, which forms a new intermediate energy level and reduces the bandgap energy. 43 It also proves that the heterojunction is formed between Zn 2 SnO 4 and SnS.…”

One-Step Synthesis of Hierarchical Flower-like SnO2/BiOCOOH Microspheres with Enhanced Light Response for the Removal of Pollutants

“…In recent years, bismuth (Bi)-based photocatalysts have garnered intensive attention owing to their excellent photocatalytic activities . Various Bi-based materials, such as Bi 2 WO 6 , , Bi 2 MoO 6 , , BiOCOOH, , Bi 2 Fe 4 O 9 , BiVO 4 , and BiOX (X = Cl, Br, or I), − have been synthesized for photocatalytic applications. Among these, BiOCOOH has a layered structure composed of fluorite-like layers of [Bi 2 O 2 ] 2+ that are intercalated with formic acid .…”

Visible Light-Driven Photoelectrocatalytic Water Splitting Using Z-Scheme Ag-Decorated MoS2/RGO/NiWO4 Heterostructure

“…These merits are anticipated to play a crucial role in reducing the electron/hole recombination, maximizing the light absorption capacity, and promoting the water-splitting process. MoS 2 nanosheets (NSs), a member of the TMDC family, have been explored because of their tunable band gap, high specific surface, relatively high charge-carrier mobility, and dense catalytic active sites. , However, the PEC properties of layered MoS 2 are limited by the ultrafast recombination of the photogenerated charge carriers and the photocorrosion driven by photogenerated holes. , This challenge can be overcome by heterojunctioning the MoS 2 with a suitable semiconductor to facilitate the separation of the photogenerated electron and hole pairs, which promotes the charge transfer and thus leading to consistent PEC performance. MoS 2 -based conventional heterojunction-photoactive materials such as MoS 2 /CdS, MoS 2 /ZnO, In 2 Se 3 /MoS 2 , and MoS 2 /ZnIn 2 S 4 have demonstrated a reasonable PEC performance.…”
