Peroxymonosulfate activation on the S-scheme heterojunction Bi4O5I2/TiO2 photoanode of a photocatalytic fuel cell for degradation of tetracyclines with green power generation.

Photocatalytic fuel cells (PFC) are green devices for simultaneous contaminant degradation and power generation. However, their performance is still limited due to the inefficient light capture and poor charge transfer at photoanodes. Here, a PFC has been successfully developed using a Bi4O5I2/TiO2...
