“…Vibration peaks of H 2 O and CO 2 adsorption centered at about 877, 1638, 1434, 3420 cm −1 are typical of bending δ(CO 3 2− ), δ(H−O−H), and stretching ν(CO 3 2− ), ν(H−O−H), respectively [19,37] …”

“…* Stretching vibrations of oxide species located at about 428 and 564 cm À 1 are attributed to ν(TbÀ O) and ν(FeÀ O), respectively; [19,27] * Vibration peaks of H 2 O and CO 2 adsorption centered at about 877, 1638, 1434, 3420 cm À 1 are typical of bending δ(CO 3 2À ), δ(HÀ OÀ H), and stretching ν(CO 3 2À ), ν(HÀ OÀ H), respectively.

Recent advancements in CeO2-enabled liquid acid/base catalysis

“…18,31,32 Additionally, reviews on characteristic reactions catalyzed by CeO 2 -based catalysts, including CO 2 conversion, CO oxidation, and selective hydrogenation, have also been published to illuminate their remarkable process. 19,33–37 Furthermore, other applications of CeO 2 in photocatalysis or biomedicine are also summed up. 38,39 However, most reviews have focused on the discussion of the reversible redox properties of CeO 2 -based materials and their potential applications based on high OSC; few systematically investigate the acid/base properties of CeO 2 for catalytic reactions, particularly in heterogeneous liquid catalysis at low temperatures.…”

CeO2-Supported TiO2−Pt Nanorod Composites as Efficient Catalysts for CO Oxidation

“…In comparison, as a unique rare metal oxide, CeO 2 has been applied as a superior reducible supporting oxide due to its rich reservation and fast storage/release oxygen ability [ 27 ]. More importantly, the reversible Ce 3+ /Ce 4+ redox reaction and easy generation of oxygen vacancies in CeO 2 can contribute to the improvement in CO oxidation rate [ 28 , 29 ]. Previous studies also imply that the morphology and facets of CeO 2 -based nanocomposites can greatly influence the formation and migration of surface oxygen vacancies, and nanosized structured CeO 2 materials, including nanospheres, nanorods, and nanocubes [ 30 , 31 ], have been synthesized.…”
