A dual-chambered hybrid system of photocatalytic fuel cell (PFC) and electro-Fenton (EF) process has become an emerging sustainable green approach for organic pollutant degradation and electricity generation. This hybrid system of PFC and EF (PFC-EF hybrid system) is an integration of two popular organic pollutants treatment methods, PFC and EF process. The double-cathodes configuration of PFC-EF hybrid system enhanced the oxygen reduction reaction reactivity in both PFC and EF. PFC-EF hybrid system with double cathodes achieved colour removal efficiencies of 86.2% and 84.7% in PFC and EF. Power density of 1.2211 μW cm-2 was obtained in this PFC-EF hybrid system. Results revealed that this PFC-EF hybrid system was effective in the Amaranth dye degradation and power production simultaneously.
