AI Technical Summary
Existing CO2 capture technologies, particularly amine-based post-combustion capture (PCC), face high energy consumption and catalyst dissolution issues during the desorption process, limiting their efficiency and economic viability.
Development of a supported Zr-based catalyst, preferably containing ZrO(OH)2, which is synthesized at a specific pH and deposited on a high-surface-area support, enhancing catalytic activity and stability, allowing for CO2 desorption at lower temperatures and reducing energy requirements.
The supported Zr-based catalyst significantly increases CO2 desorption rates at low temperatures, reduces energy costs, prevents solvent degradation, and facilitates catalyst separation, thereby improving the efficiency and cost-effectiveness of CO2 capture processes.
