【摘要】 污染控制的重要性不言而喻,但是其效果却因能耗和成本的制约而大打折扣。催化降解及高级氧化是处理难降解污染物常用的方法,引发催化降解的方法有电场电压光照辐射和化学反应。为光电催化的效率,大量的研究对催化剂的组成结构进行研究,以降低催化电压及能耗,拓展光响应范围,更好利用可见光。为了节能,人们研究了光催化燃料电池微生物燃料电池和太阳能电池,这些技术开发研究,不同程度的节约能耗并提高了降解效果。本研究发现,三元异质结光催化剂Ag/Bi VO4/Graphene具有更高的催化活性,在负载于电极上以后,作为阴极与微生物燃料电池耦合,在源于生物产电的电子输入的情况下,获得了更高的模型污染物四环素的降解和去除效率。用一小片催化电极(6-10cm2)30-60分钟去除400ml溶液中60%的四环素污染物。更多还原

【Abstract】 No need to remind us the importune of control pollutions,but current situations is not satisfactory,mainly because of the high energy-consumption and cost.Catalytic/Advanced oxidations are commonly used,with supplied electricity,light irradiation and chemicals.The photo-electro-catalytic efficiency can be improved by optimizing the structure and property,so that the energy consumptions can be reduced,the light response can be extended,and visible light be better used.Fuel cell type reactors and microbial fuel cells had been developed,these studies had led to energy-savings and more efficient pollutants removal.We find that triple heterojuctions catalysts Ag/Bi VO4/Graphene had higher activity in catalytic degradation of pollutants,and once loaded on electrode and coupled in microbial fuel cell as cathode,the capacity for degradation of pollutants was increased significantly,because of the electron instill from bio-anode to the heterojuction catalyst.更多还原
