Engineering beneficial structures and morphologies of M-N-C oxygen-reduction catalysts derived from different metal-containing precursors
Abstract Morphologies and structures of M-N-C catalysts are the key factor for controlling the formation of catalytic active sites, which are directly connected with the electrocatalytic activities for oxygen reduction reaction (ORR). By combining different metal sources (metal-free, Co, and Fe) wit...

| 520 | |a Abstract Morphologies and structures of M-N-C catalysts are the key factor for controlling the formation of catalytic active sites, which are directly connected with the electrocatalytic activities for oxygen reduction reaction (ORR). By combining different metal sources (metal-free, Co, and Fe) with polyaniline (PANI) and para-phenylenediamine functionalized GO (PGO), morphologies and structures are tuned to accelerate the ORR activity. Compared with metal-free catalyst, metal-containing catalysts show better ORR performance because of the possible synergistic effect between metal and N atoms. In particular, the improved ORR activity of Fe-PANI-PGO catalyst is obtained by rotating disc electrode (RDE) at 1600 rpm in 0.1 M KOH electrolyte. The Fe-PANI-PGO electrocatalyst has the enhanced half-wave potential of 0.89 V and the high stability with only decreasing 7 mV of half-wave potential after 10,000 cycles, implying increased number and strengthened structures of active sites. Combined with various means of characterization, advantageous morphologies and structures including large electrochemically active surface area, high graphitization degree, and thick carbon structure with more pyridinic nitrogen boned with metal atoms can greatly enhance the ORR activity and stability of the catalyst.

By combining different metal sources (metal-free, Co, and Fe) with polyaniline (PANI) and para-phenylenediamine functionalized GO (PGO), morphologies and structures are tuned to accelerate the ORR activity. Compared with metal-free catalyst, metal-containing catalysts show better ORR performance because of the possible synergistic effect between metal and N atoms. In particular, the improved ORR activity of Fe-PANI-PGO catalyst is obtained by rotating disc electrode (RDE) at 1600 rpm in 0.1 M KOH electrolyte. The Fe-PANI-PGO electrocatalyst has the enhanced half-wave potential of 0.89 V and the high stability with only decreasing 7 mV of half-wave potential after 10,000 cycles, implying increased number and strengthened structures of active sites. Combined with various means of characterization, advantageous morphologies and structures including large electrochemically active surface area, high graphitization degree, and thick carbon structure with more pyridinic nitrogen boned with metal atoms can greatly enhance the ORR activity and stability of the catalyst.

By combining different metal sources (metal-free, Co, and Fe) with polyaniline (PANI) and para-phenylenediamine functionalized GO (PGO), morphologies and structures are tuned to accelerate the ORR activity. Compared with metal-free catalyst, metal-containing catalysts show better ORR performance because of the possible synergistic effect between metal and N atoms. In particular, the improved ORR activity of Fe-PANI-PGO catalyst is obtained by rotating disc electrode (RDE) at 1600 rpm in 0.1 M KOH electrolyte. The Fe-PANI-PGO electrocatalyst has the enhanced half-wave potential of 0.89 V and the high stability with only decreasing 7 mV of half-wave potential after 10,000 cycles, implying increased number and strengthened structures of active sites. Combined with various means of characterization, advantageous morphologies and structures including large electrochemically active surface area, high graphitization degree, and thick carbon structure with more pyridinic nitrogen boned with metal atoms can greatly enhance the ORR activity and stability of the catalyst.

Engineering beneficial structures and morphologies of M-N-C oxygen-reduction catalysts derived from different metal-containing precursors |
| abstract |
Abstract Morphologies and structures of M-N-C catalysts are the key factor for controlling the formation of catalytic active sites, which are directly connected with the electrocatalytic activities for oxygen reduction reaction (ORR). By combining different metal sources (metal-free, Co, and Fe) with polyaniline (PANI) and para-phenylenediamine functionalized GO (PGO), morphologies and structures are tuned to accelerate the ORR activity. Compared with metal-free catalyst, metal-containing catalysts show better ORR performance because of the possible synergistic effect between metal and N atoms. In particular, the improved ORR activity of Fe-PANI-PGO catalyst is obtained by rotating disc electrode (RDE) at 1600 rpm in 0.1 M KOH electrolyte. The Fe-PANI-PGO electrocatalyst has the enhanced half-wave potential of 0.89 V and the high stability with only decreasing 7 mV of half-wave potential after 10,000 cycles, implying increased number and strengthened structures of active sites. Combined with various means of characterization, advantageous morphologies and structures including large electrochemically active surface area, high graphitization degree, and thick carbon structure with more pyridinic nitrogen boned with metal atoms can greatly enhance the ORR activity and stability of the catalyst.
