Novel Strontium/Iron Bimetallic Carbon Composites as Synergistic Catalyst for Oxygen Reduction Reaction in Microbial Fuel Cells

A facile synthesis of FeS/Fe3C nanoparticles highly dispersed on in situ grown N-doped CNTs as cathode electrocatalysts for microbial fuel cells

“…38 Materials with multiple catalytic centers can promote the ORR over a wide pH range. 39,40 These materials can make full use of the advantages while making up for the disadvantages of each components, thus exhibiting improved electrocatalytic activity toward the ORR. Therefore, composite materials with ultra-high electrocatalytic activity can be obtained by two or more iron-based compounds.…”
