As a result of human activity, many extra carbon dioxide (CO2) is added without removing, which destroys the balance to add and remove CO2 by the natural cycle. Moreover, many studies have reported that more CO2 emissions resulted in higher CO2 concentration which has correlation with global warming. In this circumstance, there is an increasing need to remove CO2 efficiently from CO2 containing exhaust gas, such as flue gas. Herein, we report a silicon-nanowire-embedded micro-total capture system (µ-TCS) based on excellent liquid repellency of superamphiphobic silicon nanowires. In the µ-TCS based on gas-liquid flows, CO2 is selectively captured from flue gas by an absorbent, is desorbed from the absorbent, and is ultimately utilized to synthesis drug compounds, by all-connected in-situ manner. µ-TCS is expected to provide the best possible efficiency of CO2 capture and utilization known to date. |
