摘要：
A non-noble metal based 3D porous electrocatalyst is prepared by self-assembly of the liquid-exfoliated singlelayer CoAl-layered double hydroxide nano sheets (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.
