Application of high efficiency single atom catalyst Ce&Co/CN in modifying MFC cathode for practical wastewater treatment
A kind of high-efficiency bimetallic single atom catalyst Ce&Co/g-C3N4 was synthesized by cal-cination of urea and salts.The catalyst was sopported on copper sheet using PVDF as binder.This kind of cathode electrode was used to construct microbial fuel cell reactors coupling bio-electricity production and electrocatalysis,and the two stage continous operation system,that can sequentially treat saline amine wastewater.The results showed that with cathodic photo illumination,the two stages treatment(8 h hy-draulic retention time in each stage),totally removed 95.1%COD and 85.8%TN.The capacity in COD elimination per day per kg catalyst was calculated to be 53.46 kg/(kg·d).
