Fe-Cu电子协同与结构调控的碳基催化剂及其锌-空气电池性能研究
Research on Carbon-Based Catalysts with Fe-Cu Electronic Synergy and Structural Regulation for Zinc-Air Battery Performance
摘要
Abstract
A carbon-based FeCux-CNTs material,synthesized via co-precipitation and one-step pyrolysis of a ZIF-L precursor,exhibits a three-dimensional conductive network and Fe-Cu synergy.Modulating the copper doping ratio controlled both the catalyst's morphology and electronic structure.Characterization confirmed that Fe and Cu doping promoted the in-situ growth of abundant carbon nanotubes.These nanotubes interwove with the two-dimensional car-bon matrix derived from ZIF-L,forming an integrated three-dimensional network.Optimal Cu incorporation elevated the pyridinic nitrogen content and induced electron transfer from Cu to Fe sites.This effectively tailored the elec-tronic structure of the Fe active centers,boosting their oxygen reduction reaction(ORR)activity.In alkaline electro-lyte,the FeCu0.030-CNTs catalyst achieved a half-wave potential of 0.892 V,surpassing that of commercial Pt/C(0.834 V).Zinc-air batteries fabricated with this material as the air cathode demonstrated markedly higher power density,specific capacity,and cycling stability than those using a Pt/C cathode.关键词
