Abstract

Electrochemically induced pH swing can facilitate direct air capture at ambient temperature; however, the energy efficiency is compromised by the oxidation of the redox-active organic molecules. A hybrid flow cell that spatially isolates the oxygen-sensitive materials from air achieves stable CO2 capture from oxygen-containing gas streams with low energy demand.

一种用于稳定ph值波动的混合流动电池，便于直接空气捕获

电化学诱导的pH值变化有利于在环境温度下直接捕获空气；然而，能量效率受到氧化还原活性有机分子氧化的影响。混合流动电池在空间上将空气中的氧敏感物质隔离开来，实现了从含氧气流中捕获稳定的二氧化碳，且能量需求低。
