“…Nanostructure such as CdS, SnO 2 , TiO 2 , ZnS, ZnO, etc. with particular morphologies has drawn growing attention in the latest years due to their technological applications and unique optical characteristics [1][2][3][4][5]. Zinc oxide (ZnO) is a versatility of the II-VI direct band gap semiconductor with a large 3.37 eV band gap with a large 60 meV excitonic binding energy [6][7][8][9].…”

The impact of europium (Eu 3+) ion doping has been outlined in improving the structure and optical properties of macroporous honeycomb-like zinc oxide (ZnO) nanoparticles, produced by the gel-combustion technique by changing the quantity of dopant. The X-ray diffraction (XRD) research verified that the hexagonal wurtzite structure of ZnO was not disturbed by Eu 3+ substitution. Scherrer method, Scherrer plots (SP), Williamson-Hall (W-H) plots and Size-Strain plots (SSP) were used to estimate the crystallite size. Decreased crystallite size in ZnO:Eu 3+ was noticed along with lower angle shift of XRD peaks and increased lattice parameters such as unit cell volume that can be described as replacement result of Eu 3+ at Zn sites. Fourier transform infrared (FTIR) spectroscopy analysis confirmed the Eu 3+ dopant by moving the peak from 474 cm −1 to 525 cm −1. Field-emission scanning electron microscopy (FESEM) pictures verified macroporous honeycomb-like structures. UV-Visible (UV-Vis) absorption spectroscopic studies show that the ability of ZnO:Eu 3+ nanoparticles concerning the absorption of visible light increased upon Eu 3+ doping with a red shift compared to ZnO nanoparticles. Photoluminescence (PL) emission spectra of Eu 3+ doped ZnO nanoparticles exhibited five intense band emissions at 579, 591, 617, 652, and 706 nm ascribed to 5

“…In addition to carbonaceous materials and conductive polymers, coating SnO 2 particles with a uniform layer of inorganic materials (e.g., metals or metallic compounds) can also effectively alleviate the volume changes of SnO 2 and inhibit Sn coarsening among the isolated SnO 2 particles . TiO 2 is one of the most commonly used inorganic material barriers because of its ability to suppress the huge volume expansion of SnO 2 ; this is mainly due to the minuscule volume expansion (≈4%) of TiO 2 during the reaction process of x Li + + TiO 2 + x e − ↔ Li x TiO 2 (0 ≤ x ≤ 1) (TC: 335 mAh g −1 , x = 1) . The low volume change of TiO 2 during the lithium insertion–extraction processes decreases the overall volume expansion ratio of the SnO 2 /TiO 2 hybrid electrodes relative to pure SnO 2 electrodes .…”

Superior reaction reversibility of electrode materials is urgently pursued for improving the energy density and lifespan of batteries. Tin dioxide (SnO2) is a promising anode material for alkali‐ion batteries, having a high theoretical lithium storage capacity of 1494 mAh g− based on the reactions of SnO2 + 4Li+ + 4e− ↔ Sn + 2Li2O and Sn + 4.4Li+ + 4.4e− ↔ Li4.4Sn. The coarsening of Sn nanoparticles into large particles induced reaction reversibility degradation has been demonstrated as the essential failure mechanism of SnO2 electrodes. Here, three key strategies for inhibiting Sn coarsening to enhance the reaction reversibility of SnO2 are presented. First, encapsulating SnO2 nanoparticles in physical barriers of carbonaceous materials, conductive polymers or inorganic materials can robustly prevent Sn coarsening among the wrapped SnO2 nanoparticles. Second, constructing hierarchical, porous or hollow structured SnO2 particles with stable void boundaries can hinder Sn coarsening between the void‐divided SnO2 subunits. Third, fabricating SnO2‐based heterogeneous composites consisting of metals, metal oxides or metal sulfides can introduce abundant heterophase interfaces in cycled electrodes that impede Sn coarsening among the isolated SnO2 crystalline domains. Finally, a perspective on the future prospect of the structural/compositional designs of SnO2 as anode of alkali‐ion batteries is highlighted.

“…This was achieved by developing TiO 2 nanotubes, nanowires, and altering the crystal structures of material through high temperature calcination. [9][10][11][12][13][14][15][16][17][18] However, as discussed above the low electrical conductivity of TiO 2 still limits its electrochemical performance for battery application. 19 TiO 2 composites with carbon and metal oxides have demonstrated improvements in electronic conductivity, but more work is required to achieve a material which can be of technical relevance.…”
