Amorphous Fe Nanoclusters Embedded inside Balloon-Like N-Doped Hollow Carbon for Efficient Electrocatalytic Oxygen Reduction
文献摘要：
Rational designs of electrocatalytic active sites and architectures are of great importance to de-velop cost-efficient non-noble metal electrocata-lysts towards efficient oxygen reduction reaction(ORR)for high-performance energy conversion and storage devices.In this work,active amor-phous Fe-based nanoclusters(Fe NC)are elabo-rately embedded at the inner surface of balloon-like N-doped hollow carbon(Fe NC/Ch sphere)as an efficient ORR electrocatalyst with an ul-trathin wall of about 10 nm.When evaluated for electrochemical performance,Fe NC/Ch sphere exhibits decent ORR activity with a diffusion-limited current density of～5.0 mA/cm2 and a half-wave potential of～0.81 V in alkaline solu-tion,which is comparable with commercial Pt/C and superior to Fe nanoparticles supported on carbon sheet(Fe NP/C sheet)counterpart.The electrochemical analyses combined with electronic structure characterizations reveal that ro-bust Fe-N interactions in amorphous Fe nanoclusters are helpful for the adsorption of surface oxygen-relative species,and the strong support effect of N-doped hollow carbon is benefitial for accelerating the interfacial electron transfer,which jointly contributes to improve ORR kinetics for Fe NC/Ch sphere.
