报道了一种电效应，即超电容摆动吸附（SSA）效应，其允许通过导电多孔碳材料的电容充电和放电来可逆地吸附和解吸二氧化碳。当导电的纳米多孔碳材料与二氧化碳气体和含水电解质接触时，可以观察到SSA效应。对超级电容器电极充电引发电解质离子在每个多孔电极的表面处自发组织成双电层。这种双层的存在导致在超级电容器充电和放电时CO2的可逆的、选择性的吸收和释放。
An electrical effect, the supercapacitive swing adsorption (SSA) effect is reported, which allows for reversible adsorption and desorption of carbon dioxide by capacitive charge and discharge of electrically conducting porous carbon materials. The SSA effect can be observed when an electrically conducting, nanoporous carbon material is brought into contact with carbon dioxide gas and an aqueous electrolyte. Charging the supercapacitor electrodes initiates the spontaneous organization of electrolyte ions into an electric double layer at the surface of each porous electrode. The presence of this double layer leads to reversible, selective uptake and release of the CO2 as the supercapacitor is charged and discharged.
