Bimetallic metal-organic-framework-derived porous cobalt manganese oxide bifunctional oxygen electrocatalyst

Progress on Bifunctional Carbon‐Based Electrocatalysts for Rechargeable Zinc–Air Batteries Based on Voltage Difference Performance

“…[100] In addition to Fe-Co bimetals, other combinations of TM elements, such as Fe-Ni, Mn-Co, and Co-Ni, have also been reported as good bifunctional catalysts recently. [127,128] Li et al reported a simple strategy to fabricate nitrogen, sulfur, and dual metal (Fe/Ni) co-doped carbon nanocomposite as an effective bifunctional catalyst for RZABs. [96] First, 1,4-bis(1-hexy-1Himidazo-[4,5-f ] [1,10] phenanthroline-2-yl) benzene (HIPB) compounds were synthesized and used as organic ligands to generate TM-mediated imidazole-o-phenanthroline derivatives (labeled as HIPB-M).…”

Structural and compositional analysis of MOF-derived carbon nanomaterials for the oxygen reduction reaction

“…Conventionally, 0D carbon materials can be fabricated through the direct pyrolysis of MOFs with 0D structures. 19–21 However, it is crucial to note that MOFs may collapse during the pyrolysis process, particularly when they are of too small a scale, leading to potential loss of their original morphology and transformation into lumps or other substances. Therefore, the selection of suitable precursors and strict control of pyrolysis conditions are imperative to achieve in order ordered pore structures in 0D carbon materials.…”

Mechanosynthesis of a bifunctional FeNi–N–C oxygen electrocatalyst via facile mixed-phase templating and preheating-pyrolysis

“…In pursuit of a better alternative, metal-nitrogen-doped carbon (M-N-C) catalysts rose as a potential solution, with the metal component typically being cost-effective and widely available transition metals (Fe, Co, Ni, Mn, Zn, etc.). [12][13][14] The carbon matrix in M-N-Cs exhibits excellent conductivity while nitrogen-and metal-based catalytic sites enable bifunctional catalytic activity comparable to that of PGMs. 15 More specically, pyridinic and graphitic nitrogen species and metal single atom sites are responsible for the efficient ORR activity, [16][17][18] whereas metal nanoparticles facilitate OER activity.…”
