Abstract

In this work, we report the photoelectrochemical (PEC) characteristics of the few-layer MoS2 deposited on ZnO nanorod (ZnO/MoS2), synthesized with the hydrothermal and the metal-organic chemical vapor deposition method. This hybrid structure enhances the photoexcited electron–hole pair separation and the rapid transfer of charge carriers in photoelectrical cells via the built-in potential appearing on the interlayer between ZnO and MoS2. The PEC cell of ZnO/MoS2­ photoelectrode exhibits a current density of 1.15 mA·cm–2 and an efficiency of 0.61% at a potential of 0.2 V, which is 6.3 times higher compared with the photoelectrode manufactured from ZnO nanorods. From these results, we propose a potential application of MoS2 hybrid photocatalyst materials, such as metal oxides and Si, for enhancing the efficiency of PEC devices.
