We describe a mobile CO2 scrubbing platform that offers a greatly accelerated biomimetic sequestration based on a self-propelled carbonic anhydrase (CA) functionalized micromotor. The CO2 hydration capability of CA is coupled with the rapid movement of catalytic micromotors, and along with the corresponding fluid dynamics, results in a highly efficient mobile CO2 scrubbing microsystem. The continuous movement of CA and enhanced mass transport of the CO2 substrate lead to significant improvements in the sequestration efficiency and speed over stationary immobilized or free CA platforms. This system is a promising approach to rapid and enhanced CO2 sequestration platforms for addressing growing concerns over the buildup of greenhouse gas.
我们描述了一种移动 CO2 吸收平台，该平台基于自行推进的碳酸酐酶（CA）功能化微马达，提供了大大加速的仿生固碳作用。CA 的 CO2 水合能力与催化微马达的快速运动相结合，并伴随着相应的流体动力学，导致高效的移动 CO2 吸收微系统。CA 的连续运动和 CO2 基质的增强质量传递导致在固定或游离 CA 平台上的固碳效率和速度有显著提高。该系统是一种快速增强 CO2 吸收平台的有前途的方法，可解决人们对温室气体积累的日益关注。
