Heterojunction and Photothermal‐Piezoelectric Polarization Effect Co‐Driven BiOIO3‐Bi2Te3 Photocatalysts for Efficient Mixed Pollutant Removal

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The BiOIO3‐Bi2Te3 photocatalyst possesses superior photocatalytic performance and can effectively remove not only the single RhB, TCH, or Cr(VI) but also the mixture of these three pollutants, which should be attributed to the enhanced visible light absorption and high charge carrier separation efficiency under the co‐driven effect of the type‐II ...
