Here, we report acid-activated montmorillonite as a cheap, durable, abundant, and efficient heterogeneous catalyst to optimize the CO₂ desorption rate at low temperatures (≤86 °C), eventually to significantly minimize the energy penalty of amine solutions employed for CO₂ capture. The prepared catalysts do not degrade and can be easily separated by simple filtration. Detailed characterization reveals an increase in the BET surface area, mesoporosity, and surface acidity induced by the acid-activation process. These are the key catalytic properties responsible for the superior catalytic performance.

在这里，我们报告酸活化蒙脱土是一种廉价，耐用，丰富且有效的非均相催化剂，可优化低温（≤86°C）下CO _2的解吸速率，最终最大程度地降低用于CO的胺溶液的能量损失_2次捕获。制备的催化剂不降解，并且可以通过简单过滤容易地分离。详细的表征揭示了由酸活化过程引起的BET表面积，中孔性和表面酸度的增加。这些是实现优异催化性能的关键催化性能。
