Cost-effective Bi2WO6 for efficient degradation of rhodamine B and tetracycline

The morphology-controlled synthesis of nanostructured photocatalysts by an environmentally friendly and low-cost method provides a feasible way to realize practical applications photocatalysts. Herein, Bi2WO6 (BWO) nanophotocatalysts with mulberry shape, sheet-like, round-cake morphologies have been successfully synthesized through highly facile solvothermal process simply adjusting the temperature or utilizing selective addition ethylene glycol as orientation agent without using strong acids bases and/or hazardous chemicals. ratio glacial acetic acid can affect morphology oxygen vacancy content BWO, thereby influencing photocatalytic performance. activity as-prepared samples was evaluated degradation rhodamine B (RhB) tetracycline under visible-light irradiation. results indicated that all BWO exhibited morphology-associated activity, sheet-like structure obtained via treatment at 120 °C 1:3 achieved maximum specific surface area possessed abundant vacancies, exhibiting outstanding for RhB tetracycline. rate reached 100% within 20 min. To best our knowledge, this value is one most remarkable values pristine Radical capture experiments demonstrated hydroxyl radicals (·OH) play major roles compared electrons (e−) holes (h+) in process. A possible mechanism pollutants proposed better understand reaction We believe more economical, efficient greener methodology provide guidance develop favourable structure.
