On the Origin of Electrocatalytic Oxygen Reduction Reaction on Electrospun Nitrogen–Carbon Species
Dongyoon Shin,Beomgyun Jeong,Bongjin Simon Mun,Hongrae Jeon,Hyun-Joon Shin,Jaiyoon Baik,Jaeyoung Lee +6 more
TL;DR: In this article, a facile approach to the synthesis of highly active Co-modified N-C catalyst and investigated the origin of ORR activity of electrospun N−C species by removing the metal with hydroxide carbon etching and acid metal leaching.
Journal ArticleDOI
Nitrogen-Deficient ORR Active Sites Formation by Iron-Assisted Water Vapor Activation of Electrospun Carbon Nanofibers
Beomgyun Jeong,Dongyoon Shin,Myounghoon Choun,Sandip Maurya,Jaeyoon Baik,Bongjin Simon Mun,Seung-Hyeon Moon,Dang Sheng Su,Jaeyoung Lee +8 more
TL;DR: In this paper, water vapor activation was used to increase the exposed surface area of carbon nanofibers (CNFs) for oxygen reduction reaction (ORR) and observed a substantial improvement of ORR activity up to the comparable level with Pt/C.
Journal ArticleDOI
Diagnosis of the measurement inconsistencies of carbon-based electrocatalysts for the oxygen reduction reaction in alkaline media
TL;DR: In this paper, the authors provide a diagnosis of the influence of key factors in the measured ORR activity of catalysts and provide a reference for relevant comparison of ORR performance in developed catalysts.
Journal ArticleDOI
Excavated Fe‐N‐C Sites for Enhanced Electrocatalytic Activity in the Oxygen Reduction Reaction
Beomgyun Jeong,Dongyoon Shin,Hongrae Jeon,Joey D. Ocon,Bongjin Simon Mun,Jaeyoon Baik,Hyun-Joon Shin,Jaeyoung Lee +7 more
TL;DR: This study utilizes ball milling to excavate the ORR active sites embedded in Fe-modified N-doped carbon nanofibers (Fe-N-CNFs) by pulverization and believes that this simple approach is useful to improve alternative ORR electrocatalysts up to the level necessary for practical applications.
Journal ArticleDOI
The influence of a fibrous carbon envelope on the formation of CoFe nanoparticles for durable electrocatalytic oxygen evolution.
TL;DR: It is suggested that the CNFs are a medium in which OER-active CoFe alloy nanoparticles are formed homogeneously, and that carbon layers surrounding the nanoparticlesare beneficial to the stability of the CoFe-CNFs in the OER.
