Abstract
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.
期刊介绍：
The Journal of advanced oxidation technologies (AOTs) has been providing an international forum that accepts papers describing basic research and practical applications of these technologies. The Journal has been publishing articles in the form of critical reviews and research papers focused on the science and engineering of AOTs for water, air and soil treatment. Due to the enormous progress in the applications of various chemical and bio-oxidation and reduction processes, the scope of the Journal is now expanded to include submission in these areas so that high quality submission from industry would also be considered for publication. Specifically, the Journal is soliciting submission in the following areas (alphabetical order): -Advanced Oxidation Nanotechnologies -Bio-Oxidation and Reduction Processes -Catalytic Oxidation -Chemical Oxidation and Reduction Processes -Electrochemical Oxidation -Electrohydraulic Discharge, Cavitation & Sonolysis -Electron Beam & Gamma Irradiation -New Photocatalytic Materials and processes -Non-Thermal Plasma -Ozone-based AOTs -Photochemical Degradation Processes -Sub- and Supercritical Water Oxidation -TiO2 Photocatalytic Redox Processes -UV- and Solar Light-based AOTs -Water-Energy (and Food) Nexus of AOTs
