• , Huang et al. reported that BiOI microspheres served as self-sacrificing templates for in situ phase transformation and formation of phase junctions [81]. Different bismuth oxyiodides were formed as a result of this. Hierarchical BiOI, Bi4O5I2, Bi4O5I2–Bi5O7I phase-junction, and Bi5O7I may be synthesized
