Plasma-assisted assembly of CoO/TiO-NRs for photoelectrocatalytic degradation of bisphenol A in solution and muddy systems.

Herein, CoO/TiO-NRs electrodes with excellent photoresponse have been prepared via the plasma-assisted modification of CoO on TiO. With the combination of CoO and TiO, the composite electrode exhibited a red-shift phenomenon and the absorption of UV and visible light were enhanced to improve the light utilization efficiency. The Mott-Schottky diagram showed that a P-N heterojunction was successfully formed between CoO and TiO on the electrode, which inhibited the recombination of electrons and holes, and had a high photocurrent density.
