Abstract
The hole collection efficiency of water oxidation was evaluated for CuWO electrodes from comparisons of the photocurrent of HO and NaSO oxidation as well as intensity modulated photocurrent spectroscopy (IMPS) measurements. We found current multiplication using HO, however use of NaSO and IMPS revealed quantitative water oxidation at 1.23 V vs. RHE.
摘要
通过比较HO和NaSO氧化的光电流以及强度调制光电流光谱（IMPS）测量，评估了CuWO电极的水氧化空穴收集效率。我们发现使用HO时电流倍增，然而使用NaSO和IMPS显示在相对于可逆氢电极（RHE）为1.23 V时发生定量水氧化。
