dc.description.abstract | Transition-metal- and N-codoped carbon (M-N/C) catalysts have shown great promise as alternatives to Pt-based catalysts in the oxygen reduction reaction (ORR). The preparation of M-N/C catalysts by exploiting mesoporous silica templates is highly appealing as this method can generate catalysts with high surface areas, well-developed porosities, and abundant active sites. Herein, we report the relationship between the textural properties of mesoporous silica-templated Fe-N/C catalysts and their ORR activity. Iron-doped mesoporous porphyrinic carbons (Fe-MPCs) with varying textural properties were synthesized through nanocasting using mesoporous silicas as the templates and Fe porphyrin as the precursor. Fe-MPC catalysts showed excellent ORR activities with half-wave potentials reaching 0.82V and 0.90V (vs. reversible hydrogen electrode, RHE) in acidic and alkaline electrolytes, respectively. Fe-MPC catalysts with smaller particle sizes, larger mesopore sizes, and three dimensionally interconnected pore structures showed enhanced ORR activities. | - |
