Activated carbon loaded bismuth tungstate photocatalyst as well as preparation method and application thereof

The invention discloses an activated carbon loaded bismuth tungstate photocatalyst as well as a preparation method and application thereof. The loaded bismuth tungstate photocatalyst is prepared by compounding bismuth tungstate with carrier granular activated carbon. According to the invention, a sol-gel-roasting technique is adopted for preparing the activated carbon loaded bismuth tungstate photocatalyst. The invention represents the structure and morphology of the material and researches the activity thereof of visible light photocatalysis for degrading microcystic toxin MC-LR. The preparation materials adopted by the invention are all nontoxic and low-cost. The operation method is simple and easy to control. 本发明公开了种活性炭负载钨酸铋光催化剂及其制备方法与应用，其中：所述负载型钨酸铋光催化剂是通过将钨酸铋与载体颗粒活性炭复合而成；本发明通过溶胶-凝胶-焙烧技术制备了活性炭负载钨酸铋光催化剂，本发明表征了材料的结构、形貌，并研究了其可见光催化降解微囊藻毒素MC-LR的活性。结果表明，钨酸铋成功负载到了活性炭上，并且提高了可见光光催化活性。本发明所采用的制备材料均无毒且成本低，操作方法简便易控制。
