Multihole water oxidation catalysis on haematite photoanodes revealed by operando spectroelectrochemistry and DFT
Michael Graetzel, Matthew Thomas Mayer, Yimeng Ma
Water oxidation is the key kinetic bottleneck of photoelectrochemical devices for fuel synthesis. Despite advances in the identification of intermediates, elucidating the catalytic mechanism of this multi-redox reaction on metal-oxide photoanodes remains a ...
NATURE PUBLISHING GROUP2020Water Oxidation Kinetics of Accumulated Holes on the Surface of a TiO2 Photoanode: A Rate Law Analysis
Florian Le Formal, Yimeng Ma, Min Ling
It has been more than 40 years since Fujishima and Honda demonstrated water splitting using TiO2, yet there is still no clear mechanism by which surface holes on TiO2 oxidize water. In this paper, we use a range of complementary techniques to study this re ...
Amer Chemical Soc2017Kinetics of Photoelectrochemical Oxidation of Methanol on Hematite Photoanodes
Florian Le Formal, Matthew Thomas Mayer, Yimeng Ma
The kinetics of photoelectrochemical (PEC) oxidation of methanol, as a model organic substrate, on alpha-Fe2O3 photoanodes are studied using photoinduced absorption spectroscopy and transient photocurrent measurements. Methanol is oxidized on alpha-Fe2O3 t ...
