Journal ArticleDOI
The role of cobalt phosphate in enhancing the photocatalytic activity of α-Fe2O3 toward water oxidation.
Monica Barroso,Alexander J. Cowan,Stephanie R. Pendlebury,Michael Grätzel,David R. Klug,James R. Durrant +5 more
TL;DR: It is proposed that the enhanced photoelectrochemical activity of the composite electrode for water photooxidation results, at least in part, from reduced recombination losses because of the formation of a Schottky-type heterojunction.
Journal ArticleDOI
Dynamics of photogenerated holes in surface modified α-Fe2O3 photoanodes for solar water splitting
Monica Barroso,Camilo A. Mesa,Stephanie R. Pendlebury,Alexander J. Cowan,Takashi Hisatomi,Kevin Sivula,Michael Grätzel,David R. Klug,James R. Durrant +8 more
TL;DR: This paper addresses the origin of the decrease in the external electrical bias required for water photoelectrolysis with hematite photoanodes, observed following surface treatments of such electrodes, and considers two alternative surface modifications: a cobalt oxo/hydroxo-based (CoOx) overlayer, reported previously to function as an efficient water oxidation electrocatalyst, and a Ga2O3 overlayer.
Journal ArticleDOI
Charge carrier trapping, recombination and transfer in hematite (α-Fe2O3) water splitting photoanodes
TL;DR: In this paper, the relationship between PEC activity and transient measurements is discussed in terms of a phenomenological model which rationalizes the observations and in particular the impact of external potential bias on the relative rates of charge carrier trapping, recombination and interfacial transfer in hematite photoanodes for water oxidation.
Journal ArticleDOI
Back electron-hole recombination in hematite photoanodes for water splitting.
Florian Le Formal,Stephanie R. Pendlebury,Maurin Cornuz,S. David Tilley,Michael Grätzel,James R. Durrant +5 more
TL;DR: Three complementary techniques are employed to address the kinetic competition between electron-hole recombination and water oxidation for one of the most widely studied photoanode systems: nanostructured hematite thin films, and for the first time, quantitative agreement is shown between all three techniques.
Journal ArticleDOI
Dynamics of photogenerated holes in undoped BiVO4 photoanodes for solar water oxidation
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.
