Ionic liquid‐assisted synthesis of defect‐rich BiOI with controllable structure and high surface area for excellent visible‐light photocatalytic activity
Abstract:In this study, BiOI materials with controllable structure are designed by using ionic liquid as I source and template to create the surface oxygen defects, thus promoting the photogenerated carrier migration and enhancing the photocatalytic activity. The texture of BiOI is controlled by adjusting the pH values of reaction mixture and the corresponding formation mechanism is also explored based on the self‐assembly behavior of ionic liquid. It is found that the sample BiOI‐7 possesses the ultrathin nanosheets (… Show more
“…According to the mechanism study, the improvement of photocatalytic activity could be attributed to the enhancement of electrical conductivity of RGO, the surface plasmon resonance effect of Bi and the separation of photogenerated electrons by oxygen vacancy. Using 1-ethyl-3-methylimidazole iodide as I source and template agent, Zhao et al 168 prepared a BiOI with controllable structure. By generating oxygen vacancies on the surface, they effectively separated photogenerated electrons and improved the photocatalytic performance.…”
With the development of human society, the discharge of various pollutants increases gradually, which gradually worsens the environment. Nowadays, the emission of pollutants is gradually under more strict control. Bismuth-based...
