Research progress in the photocatalytic microbial fuel cell

微生物燃料电池是利用电化学技术将微生物代谢产生的能量转化为电能并同时降解环境污染物的一种理想发电装置。总结了国内外研究不多的利用半导体材料的阴极将光能引入到微生物燃料电池体系的研究,重点对其光催化微生物燃料电池的机理、光电协同产电的技术特点、目前在污染物去除方面的应用进行总结,对其发展的方向及在废水处理方面的应用进行展望。

The microbial fuel cell is a kind of ideal electricity generating device, which makes use of electrochemical technique for converting the energy produced from microbial metabolism into electrical energy and ,at the same time, degrading environmental pollutants. The research ,which has not often been underway both in China and abroad, on the introduction of electric energy to microbial fuel cell systems by using the negative electrode of semi- conductor materials is summarized. Emphases are put on the mechanism of photocatalytic microbial fuel cell, and the technical characteristics of the electricity generating by photo-electric synergistic effect. Now, its application to the removal of pollutants is summarized and its application to wastewater treatment is predicted.
