title: Quantitative hole collection for photoelectrochemical water oxidation with CuWO4.
abstract: The hole collection efficiency of water oxidation was evaluated for CuWO4electrodes from comparisons of the photocurrent of H2O2and Na2SO3oxidation as well as intensity modulated photocurrent spectroscopy (IMPS) measurements. We found current multiplication using H2O2, however use of Na2SO3and IMPS revealed quantitative water oxidation at 1.23 V vs. RHE.
