Abstract

The invention belongs to the technical field of fuel cell catalysts, and in particular relates to a synthesis method and application of a copper polyphenol-triazine supramolecular network structure nanocomposite material. The method comprises the following steps: weighing 1,3,5-triazine-2,4,6-triamine and saturated polycyclic ketone, reacting to obtain covalent triazine-based organic polymer CTP; making CTP into CPT-polyphenol solution ; Combine the copper polyphenol solution and the CPT polyphenol solution to react; centrifuge and dry the product obtained from the reaction to obtain a precursor; the precursor is calcined under an inert atmosphere to obtain a copper polyphenol triazine supramolecular network structure nanocomposites. The present invention uses a covalent triazine-based organic polymer as the base material, and obtains a nanocomposite material with excellent oxygen reduction performance through the functional modification means of the polyphenol network, and realizes the combination of the metal polyphenol network and the triazine polymer skeleton. Closely combined, it has the characteristics of cost-effective, green and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of fuel cell catalysts, and in particular relates to a synthesis method and application of a copper polyphenol-triazine supramolecular network structure nanocomposite material. Background technique [0002] In the historical development of human society, the contradiction between energy crisis and environmental pollution has always been the main driving force for scientists around the world to study. With the depletion of traditional fossil fuels, it is imminent to develop clean and efficient energy storage and conversion technologies. Among many new energy technologies, fuel cells and electrolyzed water technologies have been studied most as sustainable and environmentally friendly energy conversion technologies. At present, the main problem of fuel cells is the cathode electrocatalyst, in which the kinetics of the cathode oxygen reduction reaction (Oxygen Reduction Reaction, ORR) is sluggish, so in order ...
