Bi2S3–In2S3 Heterostructures for Efficient Photoreduction of Highly Toxic Cr6+ Enabled by Facet‐Coupling and Z‐Scheme Structure

“…[ 19 ] Bi 2 S 3 is another transition metal sulfide similar to In 2 S 3 with a narrow bandgap (≈1.3 eV), can be synthesized with good crystallinity through facile one‐pot hydrothermal method, and was demonstrated to form heterojunction with In 2 S 3 . [ 20,21 ] For instance, Fu et al. fabricated hierarchical Bi 2 S 3 nanoflower/In 2 S 3 nanosheet composites with high visible‐light photocatalytic activity through a one‐step synthesis method.…”

Tuning the Conduction Band Potential of Bi‐based Semiconductors Using a Combination of Organic Ligands

“…Besides the characteristic properties like large specific surface area, high porosity, adjustable structure‐function etc., [2] MOFs are attracting more and more attention as a semiconductor, which is able to drive many reduction [3,4] and oxidation [5,6] reactions under light irradiation. Many bismuth based compounds are proved to be efficient photocatalysts, such as Bi 2 O 3 , [7] Bi 2 S 3 , [8] Bi 2 O 2 CO 3 , [9] BiVO 4 , [10] Bi 2 WO 6 , [11] BiOIO 3 [12] and BiOX (X=Cl, Br, I) [13] . However, though BiOBr with oxygen vacancies are reported to be able to transform N 2 to NH 3 photocatalytically, [14] Bi‐based photocatalysts are rarely reported to directly drive reduction reactions, such as CO 2 reduction, H 2 evolution from water etc.…”
