Dicaesium silver hexabromobismuthate is an inorganic compound with the formula Cs2AgBiBr6. Being a stable double perovskite material, it is applied to photocatalytic reduction of carbon dioxide.[1]

Synthesis

Dicaesium silver hexabromobismuthate can be synthesized by mixing stoichiometrical caesium bromide, silver bromide and bismuth(III) bromide in 48% hydrobromic acid.[2] Its nanocrystals can be prepared using the hot-injection method in organic solvent at higher temperature.[1]
