Abstract
Flower-structured BiOBr photocatalyst has been synthesized successfully with Gemini surfactant as bromine source through chemical precipitation procedure. The structure, morphology and optical absorption property of the product have been characterized. The results reveal that the product is pure tetragonal phase BiOBr with band gap energy (Eg) of 2.7 eV. Gemini surfactant 1,2-bis (dodecyldimethylammonio) ethane dibromide exhibits a significantly impact on the morphology of flower-structured BiOBr. A possible formation mechanism is proposed. In addition, the BiOBr shows excellent photocatalytic activity and high stability towards rhodamine B (RhB) degradation, which can be attributed to its flower-shaped structure, low Eg, and high photocurrent density. Considering the facile and eco-friendly procedure for the fabrication of BiOBr with superior visible light-induced photoactivity, it is possible to apply this semiconductor material in the field of waste water treatment practically.
