Title: Synthesis of nano-sized crystalline oxide ion conducting fluorite-type Y{sub 2}O{sub 3}-doped CeO{sub 2} using perovskite-like BaCe{sub 0.9}Y{sub 0.1}O{sub 2.95} (BCY) and study of CO{sub 2} capture properties of BCY

Abstract

Formation of nano-sized Y{sub 2}O{sub 3}-doped CeO{sub 2} (YCO) was observed in the chemical reaction between proton conducting Y{sub 2}O{sub 3}-doped BaCeO{sub 3} (BCY) and CO{sub 2} in the temperature range 700-1000 deg. C, which is generally prepared by wet-chemical methods that include sol-gel, hydrothermal, polymerization, combustion, and precipitation reactions. BCY can capture CO{sub 2} of 0.13 g per ceramic gram at 700 deg. C, which is comparable to that of the well-known Li{sub 2}ZrO{sub 3} (0.15 g per ceramic gram at 600 deg. C). Powder X-ray diffraction (PXRD), energy dispersive X-ray analysis (EDX), laser particle size analysis (LPSA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and ac impedance spectroscopy were employed to characterize the reaction product obtained from reaction between BCY and CO{sub 2} and subsequent acid washing. PXRD study reveals presence of fluorite-like CeO{sub 2} (a=5.410 (1) A) structure and BaCO{sub 3} in reaction products. TEM investigation of the acid washed product showed the formation of nano-sized material with particle sizes of about 50 nm. The electrical conductivity of acid washed product (YCO) in air was found to be about an order higher than the undoped CeO{sub 2} reported in the literature. - Graphical abstract: Transmission electronmore » microscope (TEM) image of the fluorite-type Y{sub 2}O{sub 3}-doped CeO{sub 2} (YCO) powder prepared by the reaction between proton conducting BCY and CO{sub 2} in the temperature range 700-1000 deg.
