Among the various hydrogen production technologies, there is a method of producing hydrogen using photocatalysts by water splitting. ZnO has suitable conduction band, valence band and outstanding stability. MoS2 can be utilized to excellent cocatalyst for hydrogen production. In this work, heterostructure 2D/2D ZnO/1T-MoS2 photocatalyst was synthesized via a sequential fabrication approach. First, 2D ZnO nanosheets were produced by precipitaion methods using zinc precursor and NaOH. On the other side, 2D 1T-MoS2 nanosheets were also prepared by hydrothermal methods. After that, ZnO/1T-MoS2 heterostructure was formed by sonochemical method. The weight ratios of ZnO/1T-MoS2 were controlled by their feedstocks. The synthesized photocatalysts were examined by SEM, TEM, XRD, UV-vis, and the hydrogen production rate was measured by gas chromatography under solar simulator. |
