“…Indeed, replacing the graphite foil between the die and the sample by boron nitride or alumina powder allows to reduce the Sn amount but it is still possible to find some metal tin in the core of pellets. Moreover, similar results have been obtained for higher pressure (100 MPa) and with the nanoparticles synthesized using Dujardin et al's route [38].…”

“…Two kinds of SnO2 powders have been used for this study. The first one is from Aldrich (≥ 99.9 % purity, ≈ 325 mesh, 50-200 nm grain size) and is similar to the commercial powder used by Park et al [36], and the second one was nanopowder synthesized according to the process described by Dujardin et al [38] (figure 1). Briefly, it consists in precipitating SnO2 nanoparticles (4-6 nm) from the dropwise addition of a 1 M NaOH aqueous solution into a 2 M SnCl4 aqueous solution at 373 K under reflux.…”

The spark plasma sintering (SPS) behaviour of pure SnO2 has been studied. Two different SnO2 powders have been studied: a commercial 50-200 nm one and 4-6 nm nanoparticles obtained by precipitation. It has demonstrated that it is not possible to keep pure SnO2 above 1223 K by SPS. Indeed, at 1248 K, SnO appears whereas at higher temperatures, samples are composed by SnO2 and metal Sn. Three different cycles have been

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...
