The Synthesis of Lithium Aluminate Materials and its Performance of CO₂ Absorption

Abstract:

Use Nanoscale α-Al2O3 as raw materials, prepared by high temperature solid state reaction, we produced the Lithium Aluminate (Li5AlO4) which can directly absorb CO2 at a temperature between 450°C and 650°C. Respectively use the method of scanning electron microscopy (SEM)、X-ray powder diffractometer (XRD) and thermogravimetric analyzer (TG) for the morphology、structure and the performance of CO2 absorption analysises. The results show that the synthesized Lithium Aluminate (Li5AlO4) materials have a performance of CO2 absorption.
