One-step Synthesis of Composited MoS2/TiO2 Nanotube Arrays and Its Photoelectrochemical Properties

doi:10.7517/j.issn.1674-0475.180107

Abstract

Abstract: In this paper, MoS₂ nanoparticles were successfully deposited on TiO₂ nanotube arrays by anodic oxidation method and cyclic voltammetry method, obtaining MoS₂/TiO₂ composited nanotubes. Compared with the unmodified TiO₂ nanotube arrays, the photoelectrochemical properties and photocatalytic propeties of the composited MoS₂/TiO₂ nanotube arrays have been significantly improved. The results of photocurrent experiments showed that the photocurrent density of MoS₂/TiO₂ composited nanotubes is the highest (0.35 mA/cm²) when the deposition number of MoS₂ cycles is 30 cycles, which is 3.88 times as much as the unmodified TiO₂ (0.09 mA/cm²). The MoS₂/TiO₂ composited nanotubes exhibited improved photocatalytic degradation efficiency than that of unmodified TiO₂ by comparison tests of photocatalytic degradation of 4-nitrophenol. The enhanced photoelectrochemical and photocatalytic activity is attributed to the enhanced visible absorption capacity, as well as the faster migration rate of electrons and holes on the MoS₂/TiO₂ composited nanotubes.
