Abstract
There is an urgent need to develop efficient electrocatalysts to promote the conversion and storage of green energy for achieving zero carbon emissions. Covalent organic frameworks (COFs) possess highly porous structures, while carbon nanotubes (CNTs) exhibit excellent stability and conductivity. The combination and synergistic effect of these materials can significantly enhance electrocatalytic performance in water splitting. In this study, a composite of TAPT-BMTA COF and CNT was synthesized and systematically characterized using powder X-ray diffraction, thermogravimetric analysis, and nitrogen adsorption measurements. Furthermore, we investigated the influence of pyrolysis temperature on the electrocatalytic performance by pyrolyzing the COF@CNT composites at various temperatures. The results demonstrated that the COF@CNT-600 sample exhibited superior electrochemical activity, with an OER overpotential of 321 mV and an HER overpotential of 71.6 mV at a current density of 10 mA cm-2.
