On the performance of vertical MoS2 nanoflakes as a photoelectrochemical studies for energy application

Abstract

With the help of a hydrothermal process, we were able to prepare vertically layered MoS₂ nanoflakes that were rooted to TiO₂ modified. MoS₂ nanoflakes and TiO₂ contribute significantly to the strong XRD peaks and μ-Raman spectroscopy, and this phenomenon may also be explained by the unique structure of vertically stacked MoS₂ nanoflakes on TiO₂ that has many exposed edges and large surfaces as well as high electron transfer rates between TiO₂ and MoS₂. As can be clearly seen, there are no noticeable changes in the self-photodegradation of MB under visible light interaction (VLI), and the MoS₂ doped TiO₂ photocatalyst displays ∼ 90 % degradation efficiency. By, measuring photoelectrochemically, charge carriers are separated efficiently. These experiments illustrate the transient photocurrent response of the MoS₂ doped TiO₂ photocatalyst while cycling between three on/off cycles. As a result of a low recombination rate of the photoexcited charge carriers, the MoS₂ doped TiO₂ photocatalyst displays superior photocurrent response. In other words, a lower charge transfer resistance results in a faster transfer of charge between the surfaces.
