Nanocrystaline solid solution CeO2–Bi2O3 [PDF]

Journal of the European Ceramic Society, 2012
Abstract Nanocrystalline powders of solid solution CeO 2 –Bi 2 O 3 were synthesized by self-propagating room temperature reaction (SPRT) procedure with composition (Ce 1− x Bi x O 2− δ where the x  = 0.1–0.5).

Tetravalent doping of CeO2 : the impact of valence electron character on group IV dopant influence [PDF]

, 2013
Fluorite CeO2 doped with group IV elements is studied within the density functional theory (DFT) and DFT + U framework. Concentration-dependent formation energies are calculated for Ce(1-x)Z(x)O(2) (Z = C, Si, Ge, Sn, Pb, Ti, Zr, Hf) with 0

CeO2-TiO2 Photocatalyst: Ionic Liquid-Mediated Synthesis, Characterization, and Performance for Diisopropanolamine Visible Light Degradation

Bulletin of Chemical Reaction Engineering & Catalysis, 2018
CeO2-TiO2 photocatalyst with Ce:Ti molar ratio of 1:9 was synthesized via co-precipitation method in the presence of 1-ethyl-3-methyl imidazolium octylsulfate, [EMIM][OctSO4] (CeO2-TiO2-IL). The ionic liquid acts as a templating agent for particle growth.

The tuned selective catalytic reduction behaviors of NO over the Pt/CeO2 catalysts by preferentially exposing different facets of CeO2 supports

Catalysis Communications, 2022
For the Pt catalysts supported on CeO2 nanosheet (NS), nanopolyhedron (NP) and nanorod (NR) with preferentially exposed {100}, {111} and {110} facets, respectively, the NO conversion and N2 selectivity for NO + CO reaction at 100–250 °C exhibit the order

Synthesis and catalytic performance of CeOCl in Deacon reaction [PDF]

, 2013
Surface chlorinated CeO2 is an efficient material for HCl oxidation, which raises the question whether an oxychloride phase could be also active in the same reaction.

Mixed valency in cerium oxide crystallographic phases: Determination of valence of the different cerium sites by the bond valence method [PDF]

, 2008
We have applied the bond valence method to cerium oxides to determine the oxidation states of the Ce ion at the various site symmetries of the crystals.

Ultrasonically-assisted synthesis of CeO2 within WS2 interlayers forming type II heterojunction for a VOC photocatalytic oxidation

Ultrasonics Sonochemistry, 2023
Here, we investigate the band structure, density of states, photocatalytic activity, and heterojunction mechanism of WS2 with CeO2 (CeO2@WS2) as a photoactive heterostructure.
