Bismuth oxyhalide
Bismuth oxochloride (BiOCl, bismoclite) is a rare example of a mineral oxohalide. The crystal structure has a tetragonal symmetry and can be thought of as consisting of layers of Cl , Bi and O ions, in the order Cl-Bi-O-Bi-Cl-Cl-Bi-O-Bi-Cl. This layered, graphite-like structure results in a relatively low hardness of bismoclite (Mohs 2–2.5) and most other oxohalide minerals. Those other mine… WebJan 1, 2024 · The typical bismuth oxyhalides possess open crystalline layered structures with bismuth-oxygen layer (such as [Bi2 O 2] 2+, [Bi 3 O 4] + and [Bi 12 O 17] 2+) sandwiched between two slices of halogen atoms through strong electrovalent bonds ( Fig. 1 a–b) [ [18], [19], [20], [21], [22], [23], [24]].

WebOct 15, 2024 · Bismuth oxyhalide, as a remarkably multi-component V–VI–VII semiconductors, have been extensively studied due to typical layered structure and superior carrier transport properties [18]. They have excellent chemical stability, nontoxicity, and resistance to corrosion. The nature of metallic bismuth could well be due to instability of the material under incident X-rays resulting in photoreduction to metallic bismuth. This has been observed before in bismuth based materials and also in similar compounds such as CH 3 NH 3 PbI 3 where a metallic lead signal is found. 56,57 Fig. … See more Traditional methods to visible light active materials have involved modifying wide gap semiconductors such as TiO2 and ZnO through doping, … See more
