Ionic liquid-induced strategy for porous perovskite-like PbBiO2Br photocatalysts with enhanced photocatalytic activity and mechanism insight

A novel perovskite-like PbBiO 2 Br uniform porous microspheres photocatalyst was successfully prepared via ethanol glycol (EG)-assisted solvothermal method in the presence of reactable ionic liquid 1-hexadecyl-3-methylimidazolium bromide ([C 16 mim]Br) and polyvinyl-pyrrolidone (PVP) system. During the synthetic process, the ionic liquid-PVP complex system acts as the solvent, reactant and template simultaneously, and demonstrates excellent...
