WebSep 11, 2024 · Bismuth oxyhalides (BiOX, where X = F, Cl, Br, I) are interesting materials due to their layered structure, which can be useful for different applications. In this work, … 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…
WebOct 13, 2024 · However, bismuth oxyhalide materials are susceptible to photocorrosion, making the surface defects easily deactivated and therefore losing their function as active sites. Construction of deactivation-resistant surface defects on catalyst is essential for stable CO 2 photoreduction, but is a universal challenge. 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.
