“…In our case, the capacity measured in charge ͑162 A h cm −2 ͒ for a 1.6 m thin film is kept nearly constant during 50 cycles ͑Fig. A TiO 2 matrix has been used to improve the capacity retention on cycling of SnO 2 electrodes by Roginskaya et al 27 Finally, Chouvin et al found by 119 Sn Mössbauer spectroscopy that SnO is recovered in the first charge at 3.0 V. 28 In our experiments, with a change from 1.0 to 1.2 V, a partial reoxidation of tin seems to be observed because in the dQ/dV vs V profile a small shoulder starts to appear ͑Fig. The areal capacity in discharge is higher ͑180 A h cm −2 ͒ and still presents very good capacity retention on cycling ͑82%͒.…”

“…Tin(IV) oxide, SnO 2 , has seen considerable usage in composites with TiO 2 for photocatalysis, − DSSCs, − and battery applications. − In one recent study by Xu et al, N-doped TiO 2 was synthesized, followed by addition of SnO 2 of different compositions and calcination at 400 °C . The SnO 2 /N–TiO 2 composites showed superior performance for degradation of RhB under visible light irradiation as shown in Figure a.…”

Nanostructured SnO 2 thin films were widely investigated during the past decades because of its wide band gap. Accordingly, they are used in various applications such as lithium-ion batteries, [1-11] solar cells, [12-20] solar water splitting, [21] gas sensing [20,22-32] and photoluminescence. [33] Methods reported in the literature for preparing nanostructured SnO 2 thin films include solvothermal synthesis, [3,34,35] reverse microemulsion synthesis, [36] sol-gel synthesis, [37-43] sputter deposition, [28,44] chemical vapor deposition, [29,33,45] electro spinning, [46] and electro deposition. [47] Among these preparation approaches, in particular the block copolymer-assisted sol-gel chemistry approach features advantages in terms of enabling a large-scale production, since most of the sol-gel reaction can be performed without complicated equipment in ambient conditions. Moreover, it is possible to assemble inorganic clusters into thin films with well-controlled crystal sizes, composition, and homogeneity. [48] For example, Brezesinski and co-authors synthesized crack-free, mesoporous SnO 2 films by using the amphiphilic diblock copolymer poly(ethylene-co-butylene)block-poly(ethylene oxide) and the crystallization mechanisms as well as the mesostructural evolution were investigated by a specially constructed 2D small-angle X-ray scattering setup. [49] Roose and co-authors fabricated mesoporous SnO 2 electron selective contacts of perovskite solar cells based on the block copolymer poly(1,4-isoprene-b-ethylene oxide) to achieve stable perovskite solar cells, which showed good performance under UV light in an inert atmosphere. [15] Chi and co-authors synthesized a series of mesoporous SnO 2 thin films with the amphiphilic graft copolymer poly(vinyl chloride)-g-poly(oxyethylene methacrylate), which showed significantly different gassensing performances as a function of the SnO 2 porosity. [30] Although mesoporous SnO 2 thin films prepared with block copolymer templates have shown applications in many fields, the key factors governing the final film morphology during the preparation process were rarely discussed. However, a more detailed understanding of the reaction conditions for the block copolymer-assisted sol-gel chemistry approach to synthesize As a crucial material in the field of energy storage, SnO 2 thin films are widely applied in daily life and have been in the focus of scientific research. Compared to the planar counterpart, mesoporous SnO 2 thin films with high specific surface area possess more attractive physical and chemical properties. In the present work, a novel amphiphilic block copolymer-assisted sol-gel chemistry is utilized for the synthesis of porous tin oxide (SnO 2). Two key factors for the sol-gel stock solution preparation, the solvent category and the catalyst content, are systematically varied to tune the thin film morphologies. A calcination process is performed to remove the polymer template at 500 °C in ambient conditions. The surface morphology and the buried inner structure are pro...
