Abstract
Photocatalytic fuel cell as a potential green technology has been widely reported. In this work, MoS2/TiO2 and MoS2/Ni foam were successfully synthesized and acted as photoanode and cathode, respectively, the as-prepared photocatalytic fuel cell. After MoS2 is modified, the modified composite photoanode obtains higher light-harvesting, electron-hole separation efficiency and electron transport efficiency than pure TiO2 nanorod photoanode. The result indicated that the photocurrent of the MT-3 photoanode is 1.76 times higher than that of pure TiO2. The enhanced performance is attributed to the formation of heterojunction between TiO2 and MoS2 in reducing the interface charge carrier recombination and improving the light-harvesting compared with bare TiO2. The highest value of open-circuit voltage (0.7 V), short-circuit current (1.04 mA •cm−2) and actual maximum power density (0.114 mW•cm−2) was obtained by the proposed MT-MN PFC. The degradation performance of the proposed PFC system was evaluated by decomposing the model organic pollutants. As the result indicates, the degradation efficiency was 69.16% when rhodamine B (20 ppm, pH=7) was used as the model organic waste.
