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

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.
