The CO adsorption of a phenylene-bridged ordered mesoporous organosilica (PMO-benzene) was analyzed. The maximum capture capacity was 638.2 mg·g (0 °C and 34 atm). Approximately 0.43 g would be enough to reduce the amount of atmospheric CO in 1 m to pre-industrial levels. The CO adsorption data were analyzed using several isotherm models, including Langmuir, Freundlich, Sips, Toth, Dubinin-Radushkevich, and Temkin models. This study confirmed the capability of this material for use in reversible CO capture with a minimal loss of capacity (around 1%) after 10 capture cycles. Various techniques were employed to characterize this material. The findings from this study can help mitigate the greenhouse effect caused by CO.
对亚苯基桥连有序介孔有机硅（PMO-苯）的CO吸附进行了分析。最大捕获容量为638.2 mg·g（0°C和34个大气压）。约0.43 g就足以将1立方米大气中的CO量降低到工业化前水平。使用包括朗缪尔、弗伦德利希、西普斯、托特、杜比宁-拉杜舍维奇和坦金模型在内的几种等温线模型对CO吸附数据进行了分析。本研究证实了这种材料用于可逆CO捕获的能力，在10次捕获循环后容量损失最小（约1%）。采用了各种技术对这种材料进行表征。本研究的结果有助于减轻由CO引起的温室效应。
