英文摘要In this paper, the WO3/ZnIn2S4 composite with special morphology of flower-like structures was prepared by hydrothermal method and its performance of photoinduced cathodic protection (CP) and continuous CP in the dark was studied. The construction of the WO3/ZnIn2S4 composite with special morphology is based on the following considerations. Firstly, the stacking connections of the nanoflakes of flower-like structured WO3 and ZnIn2S4 forms two-dimensional electron transport channels, which is beneficial to the directional transport of photogenerated electrons; Secondly, the heterojunction electric field formed at the WO3/ZnIn2S4 interface can accelerate the separation of photogenerated carriers; Finally, taking advantage of electron storage properties of WO3 and good photoinduced CP performance of ZnIn2S4 with a relatively negative conduction band potential, the WO3/ZnIn2S4 composite with excellent performance of photoinduced CP and continuous CP in the dark is obtained. The WO3/ZnIn2S4 system can negatively shift the potential of 304 SS by 332.8 mV, and can store 0.17 C of electricity when light illumination duration is 2 h, which is enough to provide 11.88 h continuous CP for 304 SS in dark state. This study realizes long-term CP in the dark, and provides the possibility for practical application of the photoinduced CP technology.
