Solvothermal synthesis of monodisperse self-assembly CeO2 nanospheres and their enhanced blue-shifting in ultraviolet absorption

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

“…The incorporation of UV-shielding-nano CeO 2 into the PMMA polymer matrix can produce functional nanocomposites, which can be a better way of making effective solar-thermal-control-interface structures for delaying polymer degradation. Different techniques have been used for the preparation of CeO 2 , including coprecipitation, microemulsion, microwave-assisted thermal decomposition, combustion synthesis, and mechanochemical, sol-gel, hydrothermal, solvothermal and electrochemical methods [20][21][22]. Among them, the sol-gel method has been widely used because it allows the synthesis of ultrafine powders with well-controlled properties such as homogeneity, purity, microstructure, particle size, and morphology, at relatively low cost [7,[23][24][25][26].…”

Synthesis of CeO2‐Based Quantum Dots through a Polyol‐Hydrolysis Method for Fuel‐Borne Catalysts

“…This is attributed to the formation of a steric barrier from the strong hydrophilic organic ligands coated on the QDs, which prevent the growth and agglomeration of QDs. [18,28,29] The broad band at ñ = 3400 cm À1 is related to O-H stretching vibration arising from surface hydroxyl groups. A strong CeÀO absorption band at ñ % 500 cm À1 (Figure 4 b) is evidence of the formation of CeO 2 .…”

Synthesis of micron-sized porous CeO2SiO2 composite particles for ultraviolet absorption

“…Therefore, CeO 2 nanoparticles have recently attracted much attention as an inorganic UV absorbent along with titanium oxide and zinc oxide nanoparticles [5]. Nevertheless, CeO 2 nanoparticles are rarely used in commercial products such as sunscreen owing to their unnatural coverage and unnecessary catalytic activity for the oxidation of organic materials [6,7]. To address these issues, a composite of CeO 2 created with an inorganic material can reduce the unnecessary catalytic and photocatalytic activities, such as the evolution of oxygen molecules, and thus prevent the degradation of organic materials [8].…”
