TL;DR: In this paper, the dynamics of photogenerated holes in undoped BiVO4 photoanodes for water splitting were studied using transient absorption spectroscopy, correlated with photoelectrochemical and transient photocurrent data.

TL;DR: Spectroelectrochemical evidence together with density functional theory calculations show that charge accumulation determines the reaction mechanism on metal–oxide photoanodes, and features that are common to the mechanisms of water oxidation carried out by other inorganic and biological systems are revealed.

TL;DR: In this article, photo-induced absorption and electrochemical techniques were employed to analyze the charge carrier dynamics that drive photoelectrochemical water oxidation on bismuth vanadate (BiVO4), both with and without cobalt phosphate (CoPi) co-catalyst.

TL;DR: In this paper, the authors compared the dynamics of photogenerated holes in BiVO4 photoanodes with and without CoPi surface modification, employing transient absorption and photocurrent measurements on microsecond to second timescales.

TL;DR: The kinetics of photoelectrochemical oxidation of methanol, as a model organic substrate, on α-Fe2O3 photoanodes are studied using photoinduced absorption spectroscopy and transient photocurrent measurements and it is determined that rate of reaction is second order in the density of surface holes on hematite and independent of the applied potential.
