Homopiperazine grafted mesoporous materials for CO2 adsorption |
| 초록 |
Chlorofunctionalized mesoporous MCM-41, SBA-15, MCM-48 and KIT-6 were synthesized by co-condensation of 3-chloropropyl-trimethoxy-silane (CPTMS) and sodium silicate solution obtained from Rice Husk Ash (RHA) and subsequently grafted with homopiperazine (HPZ). X-ray powder diffraction (XRD) and BET results of the parent mesoporous silica suggested their closeness of structural properties to those obtained from conventional silica sources. CO2 adsorption studies of all homopiperazine grafted mesoporous silicas showed 7-10 wt% ofCO2 adsorption capacity and adsorption reaction is through the established carbamate mechanism. The order of CO2 adsorption was observed to be MCM-48/TREN ＞MCM-41/TREN ＞ SBA-15/TREN. |
