In this study, we explore the charge transfer mechanism between WO and CuO in heterostructured WO/CuO electrodes and in a WO||CuO tandem photoelectrochemical cell. The physical-chemical characterizations of the individual WO and CuO electrodes and the heterostructured WO/CuO electrode by XRD, XPS, and SEM methods confirm the successful formation of the target systems. The results of photoelectrochemical studies infer that in both the heterostructured WO/CuO electrode and WO||CuO tandem photoelectrochemical cell, the major mechanism of charge transfer between WO and CuO is a realization of the Z-scheme.
在本研究中，我们探究了异质结构WO/CuO电极以及WO||CuO串联光电化学电池中WO与CuO之间的电荷转移机制。通过XRD、XPS和SEM方法对单个WO和CuO电极以及异质结构WO/CuO电极进行的物理化学表征证实了目标体系的成功形成。光电化学研究结果表明，在异质结构WO/CuO电极和WO||CuO串联光电化学电池中，WO与CuO之间电荷转移的主要机制均为Z型机制的实现。
