Quantitative hole collection for photoelectrochemical water oxidation with CuWO4.
Yuan GaoThomas W HamannPublished in: Chemical communications (Cambridge, England) (2018)
The hole collection efficiency of water oxidation was evaluated for CuWO4 electrodes from comparisons of the photocurrent of H2O2 and Na2SO3 oxidation as well as intensity modulated photocurrent spectroscopy (IMPS) measurements. We found current multiplication using H2O2, however use of Na2SO3 and IMPS revealed quantitative water oxidation at 1.23 V vs. RHE.
