The invention discloses a method for preparing a
copper hydroxide two-dimensional
nanocomposite material based on iron-based
dopamine supramolecular modification, which uses CuCl 2 , PEG, etc. as raw materials to prepare Cu(OH) 2 nanosheets, which were then dispersed in absolute
ethanol to obtain Cu(OH) 2 solution, then add
dopamine and Fe(NO) 3 9H 2 O, through
hydrothermal reaction and heat treatment, a 2D material that can be used as a fuel
cell anode material is finally prepared Cu(OH)2 @PDA‑Fe. The
composite material obtained in the present invention has higher initial potential, half-slope potential, excellent
limiting current, excellent stability and good
methanol tolerance, has strong resistance to
methanol poisoning, etc., and can solve the problem of existing
fuel cells. The catalyst has problems such as single precursor, high cost and
toxicity of Pt-based catalytic materials, and it is expected to be used to replace Pt / C catalysts.
