摘要：
Porous materials of PEI(n)/Zr-(N)-KIT-6 were prepared by doping zirconium to the KIT-6 framework and introducing poly(ethylenimine) (PEI) to the pore channels (n is the weight percentage of PEI to Zr-(N)-KIT-6, and N is the molar ratio of Zr/Si). The adsorbents were characterized and tested at a 20% CO2 concentration to investigate the influence of Zr and PEI on CO2 adsorption. The results display that Zr-O-Si bonds are formed after the doping of Zr species. In addition, PEI is loaded on the surface through the formation of hydrogen bonds and Zr-N bonds. The synthesized PEI(n)/Zr-(N)-KIT-6 mat...
