What is it about?

CO2 mineralization, a process where CO2 reacts with minerals to form stable carbonates, presents a sustainable approach for CO2 sequestration and mitigation of global warming. From fundamental theory to experiments, we unraveled the impact of water on CO2 mineralization efficiency and found two optimal moisture conditions for ultrafast mineral carbonation.

Why is it important?

The global CO2 sequestration practice through CO2 mineralization highly depends on the efficiency of the mineral carbonation process, which is primarily controlled by water conditions. Our findings provide a unified explanation for the often-debated optimal carbonation conditions in experiments and offer crucial guidance for harnessing moisture control to achieve efficient CO2 mineralization.

Perspectives

This work is a good start for my early academic career, which encourages me to keep going on the decarbonization research for global carbon neutrality strategies.
