AI Technical Summary

Technical Problem

In the existing HMF electrocatalytic hydrogenation reaction, there is a trade-off between Faraday efficiency and activity, which leads to the lack of catalysts in practical applications, especially on electrodes with low HER overpotentials, where the Faraday efficiency of DHMF is reduced.

Method used

CuO nanowires are used as support, and metal phthalocyanine nanoparticles are bridged with 3,4-dihydroxybenzonitrile through solvothermal reaction to form a Cu@ metal phthalocyanine heterojunction catalyst, and the catalyst is obtained by electroreduction.

Benefits of technology

It has achieved the selectivity of 2,5-furandimethyl alcohol at room temperature and normal pressure, the conversion rate of 5-hydroxymethylfurfural reaches 95%, the Faraday efficiency reaches 89%, and the production cost is reduced, with good industrial application prospects.
