Using cheap and porous diatomite or zeolite as silicon sources, we prepared firstly Li4SiO4 matetials for high temperature CO2 capture through solid-state method, and mainly investigated effects of silicon sources on the CO2 absorption properties of Li4SiO4 materials. Phase composition was analyzed by X-ray diffraction, and the CO2 absorption properties were studied by the simultaneous thermal thermogravimetric analyzer (TG-DSC). The results showed that Li4SiO4 materials using zeolite as silicon source showed little CO2 absorption properties, while Li4SiO4 materials using diatomite as silicon source showed excellent CO2 absorption properties. Compared with the existing literatures, the preparation cost of Li4SiO4 materials was lowered
