摘要：
A sol-gel technique allowing the single-pot synthesis of a carbon gel-templated, Ca-based, Al 2O 3-stabilized CO 2 sorbent is reported. Upon removal of the carbon gel template via calcination in air, hollow microspheres, comprised of a nanostructured shell are obtained. The new material possesses an excellent CO 2 uptake of 0.56 g(CO 2) g(sorbent) -1 after 30 cyclic calcination and carbonation reactions. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
