Dicaesium silver hexabromobismuthate is an inorganic compound with the chemical formula Cs2AgBiBr6. Being a stable double perovskite material, it is applied to photocatalytic reduction of carbon dioxide.Zhou, L., Xu, Y. F., Chen, B. X., Kuang, D. B., & Su, C. Y. (2018). Synthesis and photocatalytic application of stable lead‐free Cs2AgBiBr6perovskite nanocrystals. Small, 14(11), 1703762.
Synthesis Dicaesium silver hexabromobismuthate can be synthesized by mixing stoichiometrical caesium bromide, silver bromide and bismuth(III) bromide in 48% hydrobromic acid.Zhang, Z., Liang, Y., Huang, H., Liu, X., Li, Q., Chen, L., & Xu, D. (2019). Stable and highly efficient photocatalysis with lead‐free double‐perovskite of Cs2AgBiBr6. Angewandte Chemie International Edition, 58(22), 7263-7267. Its nanocrystals can be prepared using the hot-injection method in organic solvent at higher temperature.
