Study and development of thin films of shape memory ceramics and superelastic zirconia

, 2023
reservedShape memory ceramic materials, including zirconia, are a unique class of materials that possess the ability to "remember" their original shape and return to it after being deformed by an external force.

Compositional and Fabrication Cycle Optimization of Ceria-Zirconia-Supported Mo-Based Catalysts for NH₃-SCR NO_x Reduction

Inorganics
The reduction of nitrogen oxides (NOx), critical pollutants from stationary to mobile sources, mainly relies on the selective catalytic reduction (NH3-SCR) method, employing ammonia to reduce NOx into nitrogen and water.

Tuning Ce‐Zr‐Al Mixed Oxide Supports to Enhance Pt‐Pd Catalyst Performance for Low‐Temperature CO and C3H6 Oxidation in Diesel Emissions

ChemCatChem, Volume 18, Issue 5, 13 March 2026.
ABSTRACT Diesel oxidation catalysts (DOCs) with low‐temperature activity are required for low‐temperature combustion diesel (LTC‐D) engine technologies to meet emission regulations. To probe the impact of oxygen availability on activity, bimetallic Pt‐Pd catalysts supported on Ce‐Zr‐Al mixed oxides with varying Ce/Zr/Al contents were systematically ...

Propane Dehydrogenation Over Reduced CeO2 and CeZrO2

ChemCatChem, Volume 18, Issue 6, 27 March 2026.
Ceria, a non‐noble metal oxide considered inactive for propane dehydrogenation, is transformed into an active catalyst via a deep, bulk‐level reduction pre‐treatment that generates new active sites and unlocks alternative low‐energy pathways for this process.

Gold catalysts supported on ceria-modified mesoporous zirconia for low-temperature water-gas shift reaction

, 2012
New gold catalytic system prepared on ceriamodified mesoporous zirconia used as water-gas shift (WGS) catalyst is reported. Mesoporous zirconia was synthesized using surfactant templating method through a neutral [C (EO) -Zr(OC H ) ] assembly pathway ...

Structural Determination, Oxygen Diffusion, and Storage Capacity of a High‐Entropy Fluorite‐Type Oxidation Catalyst

Small Structures, Volume 7, Issue 3, March 2026.
Inducing cationic high entropy on CeO2 modifies the structure, leading to increased oxygen diffusion and resistance to sintering. In turn, this leads to enhanced oxygen storage capacities without degradation, showing potential for oxidation catalysis.

Ceria–zirconia mixed oxide prepared by continuous hydrothermal synthesis in supercritical water as catalyst support

, 2012
A number of different synthetic methods have been applied to prepare ceria-zirconia and related mixed oxides. Continuous hydrothermal synthesis in supercritical water (supercritical synthesis) is a method to prepare metal oxide nanoparticles rapidly and ...

Ceria-zirconia mixed metal oxides prepared via mechanochemical grinding of carbonates for the total oxidation of propane and naphthalene [PDF]

, 2019
A series of ceria–zirconia mixed metal oxides with varying metal ratios were prepared by the calcination of precursors synthesized by mechanochemical grinding of the metal carbonates, and tested for catalytic naphthalene and propane total combustion. The

Characterization of Surface Species during Benzene Hydroxylation over a NiO-Ceria-Zirconia Catalyst

, 2021
NiO/ceria-zirconia (CZ) is a promising catalyst for the selective oxidation of benzene, as the Lewis-acidic NiO clusters can activate C–H bonds and the redox-active CZ support can activate O2 and supply active oxygen species for the reaction.
