Self-Assembly of Single-Layer CoAl-Layered Double Hydroxide Nanosheets on 3D Graphene Network Used as Highly Efficient Electrocatalyst for Oxygen Evolution Reaction

A non‐noble metal based 3D porous electrocatalyst is prepared by self‐assembly of the liquid‐exfoliated single‐layer CoAl‐layered double hydroxide nanosheets (CoAl‐NSs) onto 3D graphene network, which exhibits higher catalytic activity and better stability for electrochemical oxygen evolution reacti...

Zusammenfassung:	A non‐noble metal based 3D porous electrocatalyst is prepared by self‐assembly of the liquid‐exfoliated single‐layer CoAl‐layered double hydroxide nanosheets (CoAl‐NSs) onto 3D graphene network, which exhibits higher catalytic activity and better stability for electrochemical oxygen evolution reaction compared to the commercial IrO2 nanoparticle‐based 3D porous electrocatalyst.
