Abstract

Highlights: CO2 absorption characteristics of Li2 TiO3 with various density are investigated. The XRD analysis decides crystallographic structure of a sintered sample. The NRBS analysis evaluates the amount of CO2 absorption quantitatively. Amount of CO2 absorbed by low-density Li2 TiO3 increases with increasing humidity. High-density samples sintered above 1470 K absorb little CO2 under high humidity. Abstract: In order to investigate the CO2 absorption characteristics of the low- and high-density Li2 TiO3 samples, X-ray diffraction (XRD) and non-Rutherford backscattering spectroscopy (NRBS) analyses have been performed. Crystallographic structure of a sintered sample is decided by the XRD analysis, and the NRBS analysis has evaluated the amount of CO2 absorption quantitatively. The amount of CO2 absorption of the low-density Li2 TiO3 samples is increased with increase of the humidity. We find that the humidity has effect on CO2 absorption to the low-density Li2 TiO3 samples. On the other hand, the high-density samples sintered at temperatures higher than 1, 470 K absorb very little CO2 under high humidity conditions.
