Soybean powder enables the synthesis of Fe–N–C catalysts with high ORR activities in microbial fuel cell applications

Synergistic melamine intercalation and Zn(NO3)2 activation of N-doped porous carbon supported Fe/Fe3O4 for efficient electrocatalytic oxygen reduction

“…Finally, the powder was pyrolyzed in Ar atmosphere according to the following two-stage heating program: (1) at 550 °C for 1 h to dehydrate and carbonize the material; (2) at 1000 °C for 1 h to further activate and graphitize the material, which is due to the evaporation of zinc at high temperature (>800 °C). 39 The final product of N-doped multilayer two-dimensional porous carbon supported Fe/Fe 3 O 4 composites was successfully prepared, named Fe/Fe 3 O 4 @NC.…”

A theoretical study on the ORR electrocatalytic activity of axial ligand modified cobalt polyphthalocyanine

“…3 Consequently, researchers have been actively seeking low-cost, non-noble metal catalysts as alternatives. [4][5][6] Among the various ORR electrocatalysts currently recognized, macrocyclic MN 4 complexes have emerged as promising substitutes for Pt-based catalysts. [7][8][9][10][11][12] Since cobalt phthalocyanine (CoPc) with a CoN 4 structural unit was first reported as the cathode catalyst for FCs in 1964, 13 transition metal phthalocyanine (TMPc) has been extensively investigated.…”

Highly active N‐doped non‐precious transition metal Fe@ N–C catalysts for efficient oxygen reduction reaction in microbial fuel cells

“… 8,9 Among them, the Fe–N–C materials attracted extensive interest due to their good catalytic performance, abundant source, and environmental friendliness 10,11 . Huang et al 12 have used raw soybean powder to synthesize Fe–N–C catalysts. ZnCl 2 was used to obtain hierarchical porous Fe–N–C catalysts.…”
