Potential of Porous Co3O4 Nanorods as Cathode Catalyst for Oxygen Reduction Reaction in Microbial Fuel Cells

Potential of Porous Co3O4 Nanorods as Cathode Catalyst for Oxygen Reduction Reaction in Microbial Fuel Cells

This study aims to investigate the potential of porous Co3O4 nanorods as the cathode catalyst for oxygen reduction reaction (ORR) in aqueous air cathode microbial fuel cells (MFCs). The porous Co3O4 nanorods were synthesized by a facile and cost-effective hydrothermal method. Three different concen...
