AI Technical Summary
Existing non-metallic electrocatalysts suffer from poor conductivity and insufficient electrochemical stability in the electrocatalytic hydrogen evolution reaction, leading to a decrease in catalytic activity.
An imidazole-based covalent organic framework material is combined with MXene nanosheets through electrostatic interaction to form a covalent organic framework/MXene composite material. The catalytic active sites of the imidazole-based covalent organic framework material and the excellent conductivity of MXene are utilized to promote electron transitions and improve electrocatalytic performance.
It achieves highly efficient electrocatalytic hydrogen evolution performance, with low overpotential and good electrochemical stability, surpassing most non-pyrolytic MXene-based catalysts.
