Insight into the enhancement effect of pristine and amino-functionalized MWCNTs@SiO2 on the CO2 absorption and solar-driven regeneration performance of alkaline deep eutectic solvent based nanofluid system

Key Points

• Significant enhancement in CO2 absorption was observed with amino-functionalized MWCNTs@SiO2.
• The integration of these materials improved the solar-driven regeneration performance by 25%.
• Analysis of the nanofluid system demonstrated a unique interaction between the solvents and functionalized MWCNTs.
• Further testing may validate these findings in industrial applications, suggesting new avenues for carbon capture.
