文摘

A series of 3D hierarchical bismuth oxyiodides were fabricated. These bismuth oxyiodides include BiOI, Bi4O5I2, Bi4O5I2-Bi5O7I junction and Bi5O7I. They exhibit different microstructures and photoactivity against diverse pollutants. Charge separation efficiency is mainly responsible for their photocatalytic activity.
