Recently, the kilowatt level electrolytic water hydrogen production coupled with green oxidation to produce succinic acid/glycolic acid technology has passed the scientific and technological achievement appraisal organized by the Chemical Industry and Engineering Society of China in Beijing. The expert team believes that the process of hydrogen production by electrolysis of water coupled with oxidation is original and at the international leading level.

This technological achievement aims to address the problem of "improving efficiency and reducing costs" in hydrogen production through electrolysis of water. Based on the original idea of "coupling oxidation of hydrogen production through electrolysis of water" proposed by Academician Duan Xue, it was jointly developed by Beijing University of Chemical Technology, Tsinghua University, and Quzhou Resource Chemical Innovation Research Institute.

The main innovations of this project include the following three points.

Firstly, the original idea of coupling oxidation for hydrogen production through electrolysis of water was proposed and a coupling reaction system was developed, revealing the reaction mechanism of controllable activation of water at the anode interface to produce "active oxygen" coupled with selective oxidation of organic compounds. The innovative idea was validated in more than 30 coupling reaction systems. After process coupling, the energy consumption of hydrogen production is reduced by more than 20% compared to traditional electrolysis of water, the hydrogen production efficiency is increased by 2 to 40 times, and the hydrogen purity is greater than 99.99%.

Secondly, two types of process technology systems for coupling hydrogen production through electrolysis of water and green synthesis of degradable plastic monomers are developed. This technological achievement has created a highly active and stable anode organic oxidation and cathode efficient hydrogen production electrocatalyst, and developed two types of electrode amplification preparation methods: catalyst coating film and electrodeposition.

Thirdly, the first kilowatt level electrolytic water hydrogen production coupled oxidation reaction system is independently designed and integrated. This technological achievement has formed a prototype reactor for electrolytic water hydrogen production coupled with oxidation microchannel, developed product separation and purification technology, constructed a kilowatt level electrolytic water hydrogen production coupled succinic acid/glycolic acid green synthesis reaction device and system, and achieved single series annual production ton level preparation of succinic acid and glycolic acid.
