从水溶液中去除苯酚、重铬酸盐等污染物是目前研究的热点。与传统的高能量输入下的方法相比，通过在Ni/C阳极上独特组装的苯酚-Cr（VI）耦合氧化还原燃料电池反应器，在自供电过程中去除重铬酸盐和苯酚，苯酚发生电氧化以产生电子，然后通过阴极上的外部电路将Cr（VI）还原为Cr（III）。以0.2 M磷酸盐缓冲溶液（PBS）中的0.94 g L− 1苯酚作为阳极电解液，0.5 M H2SO 4中的0.15 g L− 1 Cr（VI）作为阴极电解液为例，可以获得0.61 V时的净功率密度为0.184 W m− 2。该系统对0.94 g L-1苯酚在132 h内的去除率为98.6%，对0.30 g L-1 Cr（VI）在60 h内的去除率为99.8%。这证实了在补料分批模式中，溶液中的苯酚和Cr（VI）污染物被有效地去除，或者化学品中所含的能量以电的形式被准确地回收。
To eliminate contaminants like phenol and dichromate from aqueous solutions is still a hot research interest. In contrast to a traditional method within high intensity of energy input, both dichromate and phenol were removed within self-powered process through a phenol-Cr(VI) coupled redox fuel cell reactor, which was uniquely assembled on Ni/C anode the electro-oxidation of phenol takes place to give electrons and then go through the external circuit reducing Cr(VI) to Cr(III) on the cathode. Taking an example of 0.94 g L−1phenol in 0.2 M phosphate buffer solution (PBS) serving as the anolyte and 0.15 g L−1Cr(VI) in 0.5 M H2SO4serving as the catholyte, a net power density of 0.184 W m−2at 0.61 V can be gained. A removal efficiency of 98.6% for 0.94 g L−1phenol within 132 h and 99.8% for 0.30 g L−1Cr(VI) within 60 h can be readily achieved in the system. This confirmed in the fed-batch mode that either the contaminants of phenol and Cr(VI) in solutions is effectively removed or the energy contained in chemicals as the form of electricity has been exactly retrieved.
