Effect of few-layer MoS₂ flakes deposited ZnO/FTO nanorods on photoelectrochemical characteristic

We report on photoelectrochemical (PEC) characteristic of a few–layer MoS 2 –flakes deposited ZnO nanorod (MS–ZNR) configuration prepared via the hydrothermal and the metal–organic chemical vapor deposition (MOCVD) approach. The MS–ZNR nanostructure exhibited enhanced photoexcited electron-hole pair separation and transfer for energy–storage/or conversion applications. Due to a suppressing the recombination mechanism of charge carriers, the PEC performance of MS–ZNR photoelectrode revealed higher photocurrent density (1.42 mA.cm –2 at 0.2 V, η = 0.91%, with 0.1 M Na 2 S electrolyte) than a ZnO NR photoelectrode. We propose a potential application of MoS 2 –flakes hybrid nanostructure as enhanced efficient, inexpensive, and non–noble metal for PEC devices.
