文摘

A novel photocatalyst of Er3+/Fe3+ co-doped porous Bi5O7I microspheres is reported. Er3+/Fe3+ co-doped Bi5O7I showed high photocatalytic performance for phenol, bisphenol A, and chloramphenicol. The upconversion effect of Er3+ generates the enhanced photocatalytic activity of Bi5O7I. The improved photocatalytic property can also be attributed the separation of photo-induced electron-hole pairs by Fe3+.
