Direct Z-scheme porous g-C3N4/BiOI heterojunction for enhanced visible-light photocatalytic activity

Constructing direct Z-scheme heterojunction photocatalysts is a highly efficient pathway to completely utilize the high redox ability of photogenerated charge carriers. Herein, a direct Z-scheme porous g-C3N4 (Pg-C3N4)/BiOI heterojunction was constructed through the in-situ growth of BiOI on the surface of Pg-C3N4. First principle density functional theory calculations indicated that charge transfer would occur from Pg-C3N4 to BiOI due to the...
