Ceria-lanthanide-silver oxides for solar thermochemical conversion of CO2

Abstract

This paper reports the thermochemical splitting of CO2 using Ce0.9Ln0.05Ag0.05O2-d materials, which are prepared by using the co-precipitation method. The phase composition and the morphology of the derived materials was analyzed using powder X-ray diffractometer and scanning electron microscope. The thermal reduction and CO2 splitting reactions were conducted by using a high temperature TGA operated in the range of 1000 to 1400 C.
