A newly developed covalent organic framework decorated with chromium for efficient methanol fuel cell.

ABSTRACT: Covalent Organic Frameworks (COFs) have emerged as a promising class of crystalline porous materials with potential applications in various fields, including catalysis, gas storage, and energy conversion. A novel COF was prepared from the reaction of terephthalaldehyde and tris(2-aminoethyl)amine and characterized using various techniques including Fourier-transform infrared spectroscopy (FT-IR), powder X-ray diffraction (PXRD), scanning electron microscope (SEM), Brunauer-Emmett-Teller (BET) surface area measurement, and thermal analysis. BET analysis revealed a surface area of 507.56 m²/g and an average pore diameter of 8.34 nm. Chromium modification applied to increase its electrocatalytic activity to be used in fuel cells applications. The electrochemical evaluation demonstrated superi
