Noble Metal-Free Ceria-Zirconia Solid Solutions Templated by Tobacco Materials for Catalytic Oxidation of CO

open access: yes, 2016
A series of ceria-zirconia solid solutions were synthesized using tobacco leaves, stems and stem-silks as biotemplates. A combination of physicochemical techniques such as powder X-ray diffraction (XRD), N2 adsorption/desorption measurement, scanning ...

Thermodynamic stability of doped ceria for solar reactors: Sublimation and surface segregation

open access: yesOpen Ceramics
The stability of ceria‑based redox oxides under high‑temperature solar‑thermal operation is crucial for fuel‑producing reactors. This study demonstrates that the gas pressure governs CeO2 sublimation from Gd0.1Ce0.9O1.95 (GDC-10) under solar ...

Energy Consumption During Nanoparticle Production: How Economic is Dry Synthesis? [PDF]

open access: yes, 2018
The production of oxide nanoparticles by selected wet-chemistry or dry processes is compared in terms of energy requirements. Clear differences arise for production using electricity-intensive plasma processes, organic- or chloride-derived flame ...

The role of ceria in promoting Ni catalysts supported on phosphate‐modified zirconia for the partial oxidation of methane

open access: yesEnergy Science & Engineering
The catalytic partial oxidation of methane (POM) is aimed at the mitigation of CH4 (a highly potent greenhouse gas) from the environment and the synthesis of syngas with a high H2/CO ratio.

Yttria and ceria doped zirconia thin films grown by pulsed laser deposition

open access: yesMaterials Research, 2013
The Yttria stabilized Zirconia (YSZ) is a standard electrolyte for solid oxide fuel cells (SOFCs), which are potential candidates for next generation portable and mobile power sources. YSZ electrolyte thin films having a cubic single phase allow reducing
