Synthesis and CO2 capture property of high aspect-ratio Li2ZrO3 nanotubes arrays

Abstract High aspect-ratio Li2ZrO3 nanotubes were prepared by hydrothermal method using ZrO2 nanotubes layers as templates. Characterizations of SEM, XRD, TEM and CO2 adsorption were performed. The results showed that tetragonal Li2ZrO3 nanotubes arrays containing a little monoclinic ZrO2 can be obtained using this simple method. The mean diameter of the nanotubes is approximately 150 nm and the corresponding specific surface area is 57.9 m2 g−1. Moreover, the obtained Li2ZrO3 nanotubes were thermally analyzed under a CO2 flow to evaluate their CO2 capture property. It was found that the as-prepared Li2ZrO3 nanotubes arrays would be an effective acceptor for CO2 at high temperature.
