Tuning branching in ceria nanocrystals [PDF]
Chemistry of Materials, 2017 Branched nanocrystals (NCs) enable high atomic surface exposure within a crystalline network that provides avenues for charge transport. This combination of properties makes branched NCs particularly suitable for a range of applications where both ...

Humidity Sensing Ceria Thin-Films [PDF]
Nanomaterials, 2022 Lowering the constitutive domains of semiconducting oxides to the nano-range has recently opened up the possibility of added benefit in the research area of sensing materials, in terms both of greater specific surface area and pore volume. Among such nanomaterials, ceria has attracted much attention; therefore, we chemically derived homogeneous ceria ...

Enhanced oxidation activity from modified ceria: MnOx–ceria, CrOx–ceria and Mg doped VOx–ceria
Applied Catalysis B: Environmental, 2016 Abstract Ceria is an important component of catalysts for oxidation reactions that proceed through the Mars-van Krevelen mechanism, promoting activity. A paradigm example of this is the VOx–CeO2 system for oxidative dehydrogenation reactions, where vanadium oxide species are supported on ceria and a special synergy between them is behind the enhanced
