Covalently grafting covalent organic framework onto carbon nanotubes as bifunctional electrocatalyst for overall water splitting
Abstract
We propose a simple strategy to fabricate a composite material consisting of amino-functionalized carbon nanotubes (NCNTs) grafted with covalently bonded Ni(II)-based covalent organic framework (COF) for electrocatalytic water splitting. The resulting electrocatalyst demonstrates remarkable catalytic efficiency in both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) under alkaline conditions.
