The weight loss of TiO2 paste after annealing was evaluated by gravimetry and was found to be 80% of the original weight before sintering.After annealing, the photoanodes were characterized before dye sensitization through UV-Vis absorbance, scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy and X-ray Photoelectron Spectroscopy (XPS).The photoanodes were dye-sensitized by immersion into 0.5 mM ethanol solution of the commercial Ru-based complex molecular N719 dye for 24 hours and then washed with ethanol to remove any excess of unabsorbed dye molecules.Dye loading was quantitatively evaluated using UV-Vis spectrophotometry after complete removal of the dye from the photoanode with 0.1 M aqueous NaOH.The DSSCs were fabricated by using the I3−/I− redox couple electrolyte, platinized FTO glass as the counter-electrode (a 5 nm thin film of Pt on FTO by sputtering), with 25 μm thick plastic spacers between the photoanode and the Pt counter electrode.The current–voltage characteristics of the fabricated cells were measured by using a Keithley 2400 SourceMeter under simulated sunlight using an ABET2000 solar simulator at AM 1.5G (100 mW cm−2) calibrated using a reference silicon cell and mechanical filters.

The STNA-based PFC system serves well as a promising technology for wastewater treatment and the present fuel cell system could utilize visible light in the near future by combining with appropriate low band-gap semiconductors to generate electrical power under solar light illumination.The specific information for the actual wastewater samples, working principle of the microbial fuel cell (MFC), SEM and TEM characterization of traditional TiO2 nanoparticulate film, SEM images of TiO2 nanotube array prepared by anodization in different electrolytes, and the stability test of the PFC system are available.Supplementary data associated with this article can be found in the online version, at
