The sluggishness of ORR necessitates the synthesis of effective and durable catalysts to intensify the reaction process without compromising cost-effectiveness. Here, cobalt and cobalt oxides were embedded on N-doped carbon microspheres (Co?N?C/CS) using cassava starch as a carbon source. The catalyst exhibits a surface area of 388.73 m2 g?1, with a predominantly mesoporous texture. The presence of the Co?N bond, along with pyridinic and graphitic nitrogen, contributes to the ORR activity by enhancing the density of active sites. The catalyst achieves a limiting current density of ?4.64mA cm?2 with an onset potential of 0.91V (vs RHE). The calculated electron transfer value of 3.74 indicates the 4e- pathway ORR mechanism supported by Co?N?C/CS. Moreover, the catalyst demonstrates a high stability in 0.1M KOH with 99% of current retention after 14000 s, exceeding commercial Pt/C. Relatively high methanol tolerance was also observed for Co?N?C/CS by the addition of 3M methanol in the electrolyte during current-time response, highlighting its suitability as a cathode catalyst for direct methanol fuel cells (DMFC). 2026 Wiley-VCH GmbH.
