Recent advances of modification effect in CoO-based catalyst towards highly efficient photocatalysis.

Tricobalt tetroxide (CoO) has been developed as a promising photocatalyst material for various applications. Several reports have been published on the self-modification of CoO to achieve optimal photocatalytic performance. The pristine CoO alone is inadequate for photocatalysis due to the rapid recombination process of photogenerated (PG) charge carriers.
