TiO2–MoS2 composites are prepared from a novel molybdenum–sulphur cluster, (NH4)2Mo3S13·2H2O, and TiOP. A composite with 0.7% loaded MoS2 showed enhanced visible light photodegradation properties.

Herein, we report the one-step solvothermal synthesis of nitrogen doped TiO2 using N-methyl-2-pyrollidone as solvent cum dopant. The method leads to higher surface area, highly crystalline anatase TiO2 with improved visible light response.

TiO2 develops a higher efficiency when doping Bi into it by increasing the visible light absorption and inhibiting the recombination of photogenerated charges. Herein, a highly efficient Bi doped TiO2 photoanode was fabricated via a one-step modified sol-gel method and a screen-printing technique for the anode of photocatalytic fuel cell (PFC). A maximum degradation rate of 91.2% of Rhodamine B (RhB) and of 89% after being repeated 5 times with only 2% lost reflected an enhanced PFC performance and demonstrated an excellent stability under visible-light irradiation. The excellent degradation performance was attributed to the enhanced visible-light response and decreased electron-hole recombination rate. Meanwhile, an excellent linear correlation was observed between the efficient photocurrent of PFC and the chemical oxygen demand of solution when RhB is sufficient.
