摘要
Li2ZrO3 nanoparticles containing Li6Zr2O7 were prepared by a biomimetic soft solution route and characterized with X-ray diffraction (XRD), transmission electron microscope (TEM) and nitrogen adsorption. The results show that the tetragonal Li2ZrO3 nanoparticles containing monoclinic Li6Zr2O7 can be obtained using this simple method. The mean diameter of the nanoparticles is approximately 90 nm and the corresponding specific surface area is 23.7 m(2) g(-1). Moreover, the Li2ZrO3 nanoparticles obtained were thermally analyzed under a CO2 flux to evaluate their CO2 capture capacity at high temperature. It was found that the as-prepared Li2ZrO3 nanoparticles would be an effective acceptor for high temperature CO2 capture. (C) 2010 Elsevier B.V. All rights reserved.
