Ternary transition metal Co-Fe-Ni sulfide as a high-performance anode in microbial fuel cells

(Co-Fe) analogue. This performance exceeds that of most previously reported carbon-based anodes. The synthesized transition metal sulfides combine ease of fabrication with outstanding electrocatalytic efficiency. Our findings highlight the underexplored potential of ternary transition metal sulfides in engineering next-generation bioelectrochemical interfaces.
