摘　　要：采用纳米Al2O3-海藻酸钠联合固定化制备小球藻胶球,并应用于微生物燃料电池阴极,以提供电子受体,考察电池的产电性能。研究结果表明:加入纳米Al2O3能提高海藻酸钠固定化小球藻胶球的比表面积,使固定化小球藻阴极MFCs输出电压由0.113 V提高到0.173 V,且电池的输出电压随着胶球粒径的减小和加入量的增加而提高,光照可降低MFCs内阻,提高产电性能。The present research investigated the performance of microbial fuel cells with nano Al2O3-alginate joint immobilized Chlorella vulgaris as cathodic microorganism.The results show that the specific surface area of sodium alginate immobilized C.vulgaris bead increases with added nano Al2O3 so that the stabilized voltage outputs rise to 0.173 V in microbial fuel cells with nano Al2O3-alginate joint immobilized C.vulgaris from 0.113 V of the alginate immobilized C.vulgaris,nano Al2O3-alginate joint immobilized C.vulgaris generates higher voltage with smaller bead diameter and more beads,and the internal resistance decreases to improve the electricity generation performance under illumination.
