Recently, Associate Professor Yongfeng Bu (Institute for Energy Research) published a research article entitled “Removing Cost Barriers to Template Carbon Synthesis for High-Performance Supercapacitors by Establishing a Zero-Emission Chemical Cycle from CO₂” in ACS Energy Letters (ACS Energy Lett. 2022, 7, 4381-4388, IF=23.991). In this study, the "green recycling template strategy" is proposed to solve the "cost and emission" problems encountered in template carbon synthesis. Jiangsu University is the first completed department of this study, and Associate professor Yongfeng Bu is the corresponding author.

A zero-emission chemical cycle was built based on CO₂ under the background of carbon neutralization, and the recycling of MgO template (including their dissolution and regeneration) and green synthesis of template carbon with high specific surface area were realized, which is expected to solve the template cost and emission problems of template carbon synthesis. The entire preparation cycle uses just H₂O, CO₂, and Mg as inputs, and the desired high-performance capacitive carbon (the others are reusable mother liquor) with consistent morphology, pore structure and conductivity can be outputted continually, creating a sustainable link between CO₂ reductions and clean-energy applications.
