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

open access: yesBulletin 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 nature of oxygen states on the surfaces of CeO2 and La-doped CeO2 [PDF]

open access: yesChemical Physics Letters, 2014
Abstract The oxygen states on CeO 2 surfaces were investigated with DFT +  U calculations. The results reveal the variable nature of the oxygen states, including the never before modeled intrinsic peroxide surface defect. Under O-rich conditions, the peroxide defects on the (1 0 0) and (1 1 0) surfaces is more stable than oxygen vacancies.

Exceptional Electro‐Optic Coefficient Unlocked via Polarization Swaying in KNbO3 Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
We present the largest reported electro‐optic response in any material to date, guided by a new design principle that exploits ultralow coercive field polarization swaying enabled by low‐symmetry ferroelectric phases in monoclinic KNbO3 thin films for energy‐efficient classical and quantum photonic integrated circuits. ABSTRACT The electro‐optic effect

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

open access: yesCatalysis 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

Atom‐Efficient Cerium‐Based Molecular Cages as Biocompatible Reactive Oxygen Scavengers

open access: yesAdvanced Healthcare Materials, EarlyView.
Discrete mixed‐valent cerium molecular cages organize accessible redox centers within confined coordination environments and scavenge superoxide, hydrogen peroxide, and hydroxyl radicals. Encapsulation of the lead cage in an ROS‐responsive DTP nanoplatform enables lesion‐associated delivery, attenuates macrophage oxidative stress and inflammation, and ...
