Tuning the Activity of Carbon for Electrocatalytic Hydrogen Evolution via an Iridium‐Cobalt Alloy Core Encapsulated in Nitrogen‐Doped Carbon Cages

12-Jan-2018 | Peng Jiang, Jitang Chen, Changlai Wang, Kang Yang, Shipeng Gong, Shuai Liu, Zhiyu Lin, Mengsi Li, Guoliang Xia, Yang ..., Advanced Materials, 2018

Abstract Graphene, a 2D material consisting of a single layer of sp2‐hybridized carbon, exhibits inert activity as an electrocatalyst, while the incorporation of heteroatoms (such as N) into the framework can tune its electronic properties. Because of the different electronegativity between N ...
