摘要：

Methyl- and nitro-group-co-functionalized CAU-10, namely CAU-10-CH3-NO2, was synthesized and compared with mono-functionalized CAU-10 derivatives, CAU-10-CH3 and CAU-10-NO2, as a CO2 adsorbent. In this study, we report that methyl and/or nitro groups could increase CO2 performance compared to that of bare CAU-10. It is supposed that the hydrophobic character of the methyl group might support selective CO2 uptake in humid conditions. Breakthrough experiments demonstrate that CAU-10-CH3-NO2, which is more hydrophobic than CAU-10-NO2, reduced the degradation of adsorption performance under dry conditions. CAU-10-CH3-NO2 was considered a candidate suitable for an actual post-combustion CO2 adsorption process.
