Synthesis of mesoporous cerium compound for CO2 capture

Abstract

A mesoporous adsorbent was simply synthesized by adding alkaline substances to cerium(III) nitric hydrate. The surface characteristics of the synthesized cerium compound were determined with BET, XRD and TEM analysis. It was found that although the specific surface areas of the synthesized cerium compounds were among about 120-200m2 per gram (BET area) which were smaller than the common used zeolite 13X (BET area 743 m2/g) and activated carbon (BET area 1079 m2/g), but the cerium compounds had excellent performances for CO2 adsorption as well as the CO2 desorption.
