摘要: 光催化燃料电池(PFC)是一种集光催化、光电转换和有机燃料电池于一体的新型装置。制备了核壳结构的Ag@Fe2O3纳米粒子,作为阴极材料组装成双室光催化电池,首次在两个电极室中分别实现了污染物净化与Ag回收功能,同时获得电能输出。结果显示,在银离子还原反应中,Ag@Fe2O3比商品Pt电极显示出了更为优异的催化性能。所以,Ag@Fe2O3可作为一种价廉、低毒、高效的PFC阴极材料,有着极大的实际应用潜力。

Abstract: Photocatalytic fuel cell (PFC) is a novel device integrating photocatalysis, photoelectric conversion and organic fuel cell. In this paper, Ag@Fe2O3 nanoparticles with core-shell structure were prepared and used to assemble a dual-chamber photocatalytic cell as the cathode material. For the first time, the pollutant purification and Ag recovery were realized in two chambers respectively, and the electric power output was also obtained simultaneously. It shows that Ag@Fe2O3 exhibits a much better catalytic performance than commercial Pt electrodes during the reduction reaction of silver ions. Therefore, Ag@Fe2O3 can be used as an inexpensive, low-toxic, and efficient cathode material in PFC device, which has a great potential for practical applications.


Key words: photocatalytic fuel cells; Ag@Fe2O3 organic degradation; silver ion reduction
