Effect of CeO2 content in morphology and optoelectronic properties of TiO2-CeO2 nanoparticles in visible light organic degradation

Comparative Analysis of Physicochemical Properties of Rutile TiO2 with Hierarchical 3D Architecture Prepared by Liquid Hydrolysis of TiCl4 and Hydrothermal Method

“…Such changes in the electronic properties may be attributed to structural differences in the materials (for example, structural defects) and particle sizes, which are likely to affect their photocatalytic properties. The E g values for anatase and rutile TiO 2 are in the range of 3.20-3.57 [29][30][31] and 3.02-3.23 eV [29,31], respectively, but strongly depend on the particle size and morphology [29,32] and the doping cation [31,33,34]. A compar- ison of experimental data with the literature data shows that the band gap energy for the TiO 2 particles obtained in our study corresponds to the range determined for rutile.…”

Synthesis and microstructure investigation of heterogeneous metal‐plasma polymer Ag/HMDSO nanoparticles

“…Enhanced performance, which makes heterogeneous nanoparticles attractive for a variety of applications that span from catalysis, optoelectronic devices, and energy harvesting to biodetection or biomedical applications, [1][2][3][4] triggered off the development of various strategies that allow their controllable synthesis. Among them, increasing attention is attracted by gas-phase condensation techniques that utilize magnetron-based gas aggregation sources (GASs).…”

“…The interest in this kind of nanomaterials is motivated by the fact that they may possess unique chemical‐, physical‐, or bio‐related properties resulting from the combination of properties of their individual counterparts as well as from mutual interactions of different constituent materials. Enhanced performance, which makes heterogeneous nanoparticles attractive for a variety of applications that span from catalysis, optoelectronic devices, and energy harvesting to biodetection or biomedical applications, 1–4 triggered off the development of various strategies that allow their controllable synthesis. Among them, increasing attention is attracted by gas‐phase condensation techniques that utilize magnetron‐based gas aggregation sources (GASs).…”

Study of obtaining thin films of CeO2 doped with 2 and 4 mol% of europium, terbium and thulium by spin coating: photocatalytic properties

“…Among its main characteristics are the high chemical resistance and the photocorrosion, high capacity of absorption of UV radiation and an excellent capacity of liberation and storage of oxygen [7]. Moreover, the ease of conversion between cerium valences (Ce 4+ /Ce 3+ ) makes it a material with high redox potential [8,9]. However, in comparison to other materials used in photocatalysis, such as TiO 2 , it presents low mobility of charges on its surface, which makes the photocatalytic process difficult [9].…”

However, in comparison to other materials used in photocatalysis, such as TiO 2 , it presents low mobility of charges on its surface, which makes the photocatalytic process difficult [9]. Modifications in the electronic structure of CeO 2 , such as doping, generate defects that alter the mobility of the charges, increasing its photocatalytic activity [10].…”
