The PPy-14%/WO3/TiO2/Ti photoanode was prepared to inhibit rapid recombination of electron-hole pairs and expand the light response wavelength, resulting in enhanced performance of the photocatalytic fuel cell.
In order to inhibit rapid recombination of electron-hole pairs of photoanode and expand its light response wavelength, PPy-14%/WO3/TiO2/Ti photoanode was prepared. The maximum photocurrent density is 2.31 mA.cm(-2), which is 1.76 times higher than that of WO3/TiO2/Ti at 1.1 V (vs. SCE). The maximum power density, phontocurrent density and Rhodamine B degradation rate of photocatalytic fuel cell (PFC) with PPy-14%/WO3/TiO2/Ti photoanode and Cu cathode are 25.48 mu W.cm(-2), 0.25 mA.cm(-2) and 88.5%, respectively. The excellent performance is mainly due to the good carrier migration rate of PPy and the synergistic effect of PPy/WO3/TiO2/Ti ternary hybrid electrode, so that photogenerated electrons and holes can accumulate in the conduction band of WO3 and HOMO of PPy, respectively. This not only expands the light absorption range and enhances the light absorption intensity, but also improves the separation of electron-hole pairs, and finally significantly enhances the Rhodamine B degradation and electricity generation performance of PFC.
