Ameliorating Cu2+ reduction in microbial fuel cell with Z-scheme BiFeO3 decorated on flower-like ZnO composite photocathode

BiFeO3 nanoparticle decorated on flower-like ZnO (BiFeO3/ZnO) was fabricated through a facile hydrothermal-reflux combined method. This material was utilized as a composite photocathode for the first time in microbial fuel cell (MFC) to reduce the copper ion (Cu2+) and power generation concomitantly...

The resultant BiFeO3/ZnO-based MFC displayed distinct photoelectrocatalytic activities when different weight percentages (wt) BiFeO3 were used. The 3 wt BiFeO3/ZnO MFC achieved the maximum power density of 1.301 W m�2 in the catholyte contained 200 mg L�1 of Cu2+ and the power density was greatly higher than those pure ZnO and pure BiFeO3 photocathodes.
