Abstract
of 0.835 V) in alkaline media. Notably, this catalyst also displays strong ORR performance similar to that of Pt/C in acidic media. The superior durability and methanol tolerance in both alkaline and acidic media for UF Co-N-C compared to Pt/C illustrate its great potential in replacing commercial Pt/C catalysts. The outstanding ORR performance of UF Co-N-C could be attributed to the simultaneous optimization of both external structures and active sites, demonstrating the effectiveness of this strategy in constructing ORR catalysts with controlled structures and desired functionalities.
