This paper proposes photocatalytic fuel cell (PFC) was proposed to remove dye contaminants and generate electricity at same time. The photoanode PFC is Carbon quantum dots (CQDs)/anatase TiO2 (A-TiO2), cathode Pt. CQDs/A-TiO2 composite structure can extend visible light absorption range A-TiO2. Different crystal structures particle sizes an effect on power generation contaminant removal performance PFC. results photodegradation experiments electrochemical tests indicate degradation electrochemistry 20 nm A-TiO2 are superior those other samples. Consequently, selected for photoanode. photocurrent density, open-circuit voltage maximum density were found be 0.6 µA/cm2, 0.41 V 0.1 µW/cm2, respectively. Photodegradation showed could contaminants.

Based on the photocatalytic activity and magnetic nature of magnetite goethite, as well oxygen storage characteristic cerianite, a ternary hybrid composite including cubic CeO2, Fe3O4 orthorhombic FeOOH, designated Fe3O4/FeOOH/CeO2, was successfully synthesized with different Ce:Fe molar ratios using simple hydrothermal route without subsequent calcination process, employed photocatalysts for degradation Acid Orange 7 (AO7) dye. The absorption range light by Fe3O4/FeOOH/CeO2 composites broadened, intensity enhanced. Furthermore, there existed possibility hybridization doping among three crystalline structures, elements Ce, Fe O exhibiting uniform distribution, significantly enhancing efficiency in promoting photodegradation AO7. response behaviors were investigated. adsorptive AO7 darkness under UV illumination evaluated. Moreover, ten cycling runs simulated ratio 1:15 performed. proved to have excellent sensitivity, exhibited outstanding activities demonstrated remarkable stability. It is anticipated that may potential applications treatment organic dye sewage.
