New Photocatalytics Study Findings Reported from Heriot Watt University (Solar photocatalytic fuel cell using CdS-TiO2 photoanode and air-breathing cathode for wastewater treatment and simultaneous electricity production)

By a News Reporter-Staff News Editor at Energy Weekly News -- Current study results on Photocatalytics have been published. According to news reporting originating in Edinburgh, United Kingdom, by VerticalNews journalists, research stated, "Solar photocatalytic fuel cell (PFC) is a promising technology for environmental-friendly wastewater treatment and simultaneous production of electricity. In this study, PFC was enhanced by using CdS quantum-dot-sensitized TiO2 nanorod array deposited onto FTO glass as effective photoanode."

The news reporters obtained a quote from the research from Heriot Watt University, "Moreover, gas diffusion electrode was employed to improve oxygen reduction reaction at the cathode. The material characterization shows that an array of 1.2-mu m TiO2 nanorods is decorated with 10-nm CdS quantum dots, which significantly improve solar light harvesting ability. The results of the PFC performance study indicate that light irradiation, acetic acid concentration, electrolyte pH and conductivity have significant influence on the short-circuit current and maximum power density. When the PFC operates at the optimum pH of 4.6, the short-circuit current and maximum power density are 1.79 mA/cm(2) and 1134 mW/cm(2), respectively. It is found that increasing the electrolyte conductivity is an effective approach to improve the PFC performance. The highest short-circuit current of 5.1 mA/cm(2) and maximum power density of 3980 mW/cm(2) are obtained with electrolyte having a conductivity of 63.1-mS/cm."

According to the news reporters, the research concluded: "In addition, the test results of various pure and practical organic substances in PFC further suggest that it is feasible to use sunlight as a driving force to clean up wastewater with simultaneous electricity production."
