Investigating the effects of in-situ fabrication of a binder-free Co3O4-polyaniline cathode towards enhanced oxygen reduction reaction and power generation of microbial fuel cells

摘要: Abstract Exploring a low-cost and highly effective technique in the construction of electrodes for enhanced oxygen reduction reaction microbial fuel cells plays crucial role power generation output cell system. In this manuscript, an in-situ synthesis Co3O4-polyaniline on surface carbon cloth is utilized binder-free electrode performance compared with prepared by coating technique. The lack costly binder like polytetrafluoroethylene structure advantage leads to low internal resistance consequently, facilitated electron/charge transfer process. various electrochemical analyses examinations, acquired demonstrates outstanding activity. as-prepared are also employed as cathode dual-chamber cell. In-situ exhibits great maximum density (102.54 mW.m−2), which 2.35 times higher than (43.6 mW.m−2). results indicate that series advantages such cost, good performance, easy fabrication could be class promising alternative strategy preparation obtain prominent output.
