Tailoring Ceria-Based Nanocatalysts for Enhanced Performance in Steam Reforming Processes: Exploring Fundamentals and Morphological Modulations

Hydrogen, 2023
Ceria-based nanostructures, employed as catalytic supports for noble and non-noble metals, are well-known for their remarkable activity in steam-reforming reactions, exceptional resistance to degradation, and thermal stability.

High electrochemical activity of the oxide phase in model ceria–Pt and ceria–Ni composite anodes [PDF]

, 2012
Fuel cells, and in particular solid-oxide fuel cells (SOFCs), enable high-efficiency conversion of chemical fuels into useful electrical energy and, as such, are expected to play a major role in a sustainable-energy future.

Stabilisierung von interstitiellen Platin‐Atomen unterhalb der CeO2(111)‐ Oberfläche: Neue Ansätze für die Architektur von Einzelatom‐Katalysatoren

Angewandte Chemie, EarlyView.
Durch die Kombination polarisationsaufgelöster IRRAS an atomar flachen CeO2(111)‐Einkristallen mit quantitativen XPS‐ und DFT‐Berechnungen identifizieren wir eine ungewöhnliche interstitielle Konfiguration von Pt‐Einzelatomen in der Subsurface‐Region, die zu einer bisher unbeobachteten, blauverschobenen CO‐Schwingungsmode führt.

Subsurface Stabilization of Interstitial Pt Atoms on CeO2(111): Rethinking Single‐Atom Catalyst Architectures

Angewandte Chemie International Edition, EarlyView.
By combining polarization‐resolved IRRAS on atomically flat CeO2(111) single crystals with quantitative XPS and DFT calculations, we identify an unusual subsurface interstitial configuration of Pt single atoms that gives rise to a previously unobserved, blue‐shifted CO vibrational mode.

Arsenic(III) adsorption from aqueous solutions on novel carbon cryogel/ceria nanocomposite [PDF]

Processing and Application of Ceramics, 2016
Carbon cryogel/ceria composite, with 10 wt.% of ceria, was synthesized by mixing of ceria and carbon cryogel (CC). The sample was characterized by field emission scanning electron microscopy, nitrogen adsorption and X-ray diffraction.

Improved Dry‐Pressing Strategy for Fabricating Double‐Sided Rough YSZ Electrolyte Thin Films and Their Performance in Solid Oxide Cells

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study addresses limitations of the conventional dry‐pressing method for electrolyte‐supported films—smooth surfaces, excessive thickness, and fragile supports inducing damage. We propose an innovative camphor–quartz sand composite architecture to construct a five‐layer (camphor/quartz sand/YSZ/quartz sand/camphor) system, enabling thin ...

Facile preparation of triangular-like polycrystalline ceria as supporting carrier in catalysis exemplified by Ni/CeO2 catalyzed oxidation and hydrogenation reactions

Sustainable Chemistry for the Environment
Ceria is a reducible oxide that has been extensively employed as supporting carrier in catalysis due to its unique redox and structural properties in combination with its strong interaction with the active phases.
