“…[10][11][12][13][14] Among the numerous UV absorbers, ceria nanoparticles are ideal candidates due to their excellent UV absorption ability, visible light transparency and lower light refractive index. [15][16][17][18] Several studies have been published on the incorporation of CeO 2 nanoparticles into polymer latex to shield UV light. [19][20][21] Most of these studies achieved good dispersion of cerium oxide via physical blending or modication with ligands or hydrogen bonds, such as citric acid, polyethylene glycol and poly(acrylate acid).…”

It is of great importance to exploit electrode materials for sodium-ion batteries (SIBs) with low cost, long life, and high-rate capability. However, achieving quick charge and high power density is still a major challenge for most SIBs electrodes because of the sluggish sodiation kinetics. Herein, uniform and mesoporous NiS nanospheres are synthesized via a facile one-step polyvinylpyrrolidone assisted method. By controlling the voltage window, the mesoporous NiS nanospheres present excellent electrochemical performance in SIBs. It delivers a high reversible specific capacity of 692 mA h g . The NiS anode also exhibits excellent high-rate capability (253 mA h g at 5 A g ) and long-term cycling performance (319 mA h g capacity remained even after 1000 cycles at 0.5 A g ). A dominant pseudocapacitance contribution is identified and verified by kinetics analysis. In addition, the amorphization and conversion reactions during the electrochemical process of the mesoporous NiS nanospheres is also investigated by in situ X-ray diffraction. The impressive electrochemical performance reveals that the NiS offers great potential toward the development of next generation large scale energy storage.

“…This is connected with fast recombination of photoinduced electron-hole pairs and limited visible light adsorption capacity [167]. CeO 2 is an n-type semiconductor with a relatively wide bandgap (E g = 3.15-3.2 eV) [167,168]. On the other hand, CeO 2 has emerged as a promising material for photocatalysis owing to its chemical stability and photocorrosion resistance [169].…”

Ag/CeO2 Composites for Catalytic Abatement of CO, Soot and VOCs

et al. 2018

Nowadays catalytic technologies are widely used to purify indoor and outdoor air from harmful compounds. Recently, Ag-CeO 2 composites have found various applications in catalysis due to distinctive physical-chemical properties and relatively low costs as compared to those based on other noble metals. Currently, metal-support interaction is considered the key factor that determines high catalytic performance of silver-ceria composites. Despite thorough investigations, several questions remain debating. Among such issues, there are (1) morphology and size effects of both Ag and CeO 2 particles, including their defective structure, (2) chemical and charge state of silver, (3) charge transfer between silver and ceria, (4) role of oxygen vacancies, (5) reducibility of support and the catalyst on the basis thereof. In this review, we consider recent advances and trends on the role of silver-ceria interactions in catalytic performance of Ag/CeO 2 composites in low-temperature CO oxidation, soot oxidation, and volatile organic compounds (VOCs) abatement. Promising photoand electrocatalytic applications of Ag/CeO 2 composites are also discussed.Au [17][18][19][20][21][22][23], Ru [24,25], Rh [26][27][28][29], and Cu [30,31] were proposed. Metal oxide-based catalysts (Co 3 O 4 [32], MnO x [33], etc.) also attracted wide interest. However, a significant part of the developed catalysts has limited use under real conditions due to high costs of noble metals (the loading of palladium, platinum, gold is of 2-10 wt. %), relatively low stability to "hard" conditions of oxidation processes causing the loss of active component and reduction of the catalyst activity and selectivity. Therefore, the development of high-performance affordable and stable catalysts for low-temperature total oxidation of harmful compounds is still challenging. Efficiency and costs of such catalysts are connected with proper selection of the type of active component, support, and preparation method [34].Recently, supported silver catalysts have brought about wide interest due to their high activity in low-temperature oxidation processes. Different supports are studied (SiO 2 , CeO 2 , MnO x , TiO 2 , Al 2 O 3 , ZrO 2 , etc.) [35][36][37][38]. It is shown that an enhanced catalytic activity of Ag-based catalysts can be achieved by using reducible metal oxides as supports and by controlling the metal-support interaction to provide synergistic effect between active sites of the support and noble metal [39].Among the supports mentioned, CeO 2 brings about high interest, since it combines exceptional redox and acid-base properties with oxygen storage, which can be controlled by proper preparation methods and treatments. Moreover, these distinctive properties of ceria cause its wide applications as a support for catalysts. For this reason, highly active and relatively inexpensive Ag/CeO 2 composite is considered promising heterogeneous catalyst for total oxidation of harmful organic compounds, including formaldehyde [40], , soot [44][45][46][47][48][49]. The Ag...
