ZnO:CeO2-based nanopowders with low catalytic activity as UV absorbers

Thermal, Mechanical and UV-Shielding Properties of Poly(Methyl Methacrylate)/Cerium Dioxide Hybrid Systems Obtained by Melt Compounding

“…As one of the most versatile semiconductors, cerium dioxide (CeO 2 ) can be used as a solar absorber. CeO 2 has shown good thermal and chemical stabilities, a high refractive index in the visible region (2.1-2.2), good transmittance in the visible spectrum and low cost due to the fact that it is one of the most abundant rare earth elements [13][14][15]. It has also potential applications such as in fuel and solar cells, catalysts, oxygen sensors, polishing agents, gate oxides, optical devices and coating materials [16][17][18].…”

Ceria Nanoshapes—Structural and Catalytic Properties

“…This is due to its unique redox properties and high oxygen storage capacity (OSC), allowing it to quickly switch oxidation state between Ce 4+ and Ce 3+ in the stable fluorite structure [10,11]. Because of these redox properties, CeO 2 is used in a wide range of applications such as an ultraviolet absorber in sun blocks [12], O 2 sensors [13,14], and antioxidant in the field of biomedicine [15]. Ceria is commercially used as a catalyst support in applications such as three-way catalysts (TWC) [16] and as solid electrolytes in low-temperature solid oxide fuel cells [17,18].…”

The influence of mechanochemical activation on the Zn–Ce–O composition properties

“…The promoted effect for ZnO-doped ceria (Kaviyarasu et al, 2016;Li et al, 2002;Lin et al, 2015) or CeO 2 -doped zinc oxide (De Lima et al, 2009;Fan et al, 2013;Saravanan et al, 2012) samples was shown, but many publications demonstrated an improvement of the composition properties at oxides equimolar ratio or near to this value (Barrios et al, 2014;Enjamuri et al, 2016;Hajji et al, 2014;Kumar et al, 2015;Laguna et al, 2011;Li et al, 2011;Li et al, 2012;Xiong et al, 2017, etc. ).…”

“…At the same time, it is generally accepted that the properties of the composites often cannot be considered as a sample superposition of the properties of individual components because of strong surface interactions between closely packed particles in binary oxide systems. Among these systems, ZnO-CeO 2 composite is one of the most promising materials which demonstrates the better properties than individual oxides at its uses as catalyst (Enjamuri et al, 2016;He et al, 2004;Kumar et al, 2015), photocatalyst (Li et al, 2012;Saravanan et al, 2012;Xiong et al, 2017), support of catalyst (Avgouropoulos et al, 2008;Barrios et al, 2014;Laguna et al, 2011), material for electrodes (Fan et al, 2013;Hajji et al, 2014), ultraviolet filter (De Lima et al, 2009;Li et al, 2002), etc.…”
