Binary ligand strategy toward interweaved encapsulation-nanotubes structured electrocatalyst for proton exchange membrane fuel cell
文献摘要：
Hierarchically porous architecture of iron-nitrogen-carbon (Fe-N-C) for oxygen reduction reaction (ORR)is highly desired towards efficient mass transfer in the fuel cell device manner.Herein,we reported a bin-ary ligand strategy to prepare zeolitic imidazolate frameworks (ZIFs)-derived precursors,wherein the addition of secondary ligand endows precursors with the capabilities to transform into porously inter-weaved encapsulation-nanotubes structured composites after calcination.The optimal catalyst,te.,ter-med as Fe6-M/C-3,exhibits excellent durability with 88.8％ current retention after 50,000 seconds in 0.1 M HClO4 solution by virtue of nanoparticles-encapsulation features,which is more positive than the benchmark commercial 20 wt％ Pt/C catalyst.Moreover,a promising maximum power density of Fe6-M/C-3 as cathode catalyst was also demonstrated in proton exchange membrane fuel cells(PEMFCs) measurements.Therefore,this binary ligand approach to the fabrication of hierarchically por-ous structures would also have significant implications for various other electrochemical reactions.
