Controlled engineering of Bi4O5Br2 and BiOBr via interactions between imidazolium ionic liquids and medium during synthesis as a simple method for enhancement of photocatalytic activity

The synthesis of Bi 4 O 5 Br 2 and BiOBr in non-polar (glycerol, ethylene glycol) and polar (0.1 M mannitol) solvents studied the impact of elongating alkyl side chains (C4mim + , C8mim + , C16mim + ) of imidazolium ionic liquids on the materials' properties.
