TL;DR: The results demonstrated that EIS is a powerful tool for studying the kinetics of PEC decomposition of organic pollutants on TiO2 electrodes and that the experimental EIS results here and those previous published on PEC degradation reactions can be explained satisfactorily.

TL;DR: In this article, the authors reported on the mechanism of water splitting by TiO2 in the absence of chemical scavengers in a fully functional photoelectrochemical (PEC) cell.

TL;DR: It was demonstrated that NO(2)(-) could be efficiently degraded on the doped photoanode that showed a higher activity than the undoped WO(3) especially under high anodic potential (>0.7 V) and the rate of degradation was enhanced in aqueous NaCl solutions.

TL;DR: In this paper, the electron diffusion length (L) relative to film thickness is measured in a nanocrystalline, mesoporous TiO2 electrode during photochemical water splitting by two independent methods: (1) analyzing the ratio of incident photon conversion efficiency measured under back and front side illumination, and (2) analyzing transient photovoltage rise and decay measurements.

TL;DR: In this article, a new and simple method for surface fluorination and porosity-creating of TiO2 is presented, where a sample was prepared by anodization of the nanoporous material in HF aqueous solutions formed by direct thermal oxidization of titanium sheet.
