Chemist Jie Zeng hopes his research will contribute to tackling climate change.

Jie Zeng and his colleagues study ways to convert carbon dioxide into fuel that could be used in batteries.Jie Zeng, a chemist at the University of Science and Technology of China in Hefei, tellsabout his efforts to capture the carbon dioxide produced by heavy manufacturing and use it productively in batteries.I study ways to convert the carbon dioxide released by cement, steel and petrochemical plants into liquid fuels and chemicals using electrical energy.

My team at USTC has tested out several generations of a technology that combines a catalyst and an electrochemical device to make formic acid — a simple, naturally occurring acid — from COOne of the historical disadvantages of the process of synthesizing formic acid using COis that the acid needs to be separated and purified from an electrolyte solution. This accounts for more than 70% of the total cost of production..

This year we reached a cooperation agreement with Sinopec, a large oil and petrochemical products supplier based in Beijing. The company is interested in using our technology to manufacture more of a set of chemicals called α-olefins. They can be made through COHow does USTC support research into carbon-neutral technologies?

In September 2020, China’s President Xi Jinping set out a goal for the country to hit peak emissions before 2030 and become carbon neutral by 2060. This has produced opportunities for domestic researchers who are working in the field of COFor example, in January 2022, USTC established its own Institute for Carbon Neutralization, which will provide financial support for the development of carbon recycling technology.

Our team’s projects are mainly funded by the National Natural Science Foundation, the Ministry of Science and Technology, the Chinese Academy of Sciences and some businesses. We receive around 10 million to 20 million yuan per year. It’s fair to say that since President Xi’s announcement, a lot more funding has arrived.conversion, which is probably my proudest achievement. Many of the greatest scientific developments require the relentless efforts of several generations of researchers.
