“…The resulting SnO 2 nanoparticles are around 5 nm in diameter and their high BET surfaces (up to 191 m 2 g À1 ) makes them promising for gassensor applications. [124] Pre-treatments of the precursors can further enhance the efficiency of MW-ST syntheses as has been shown in a combined sol-gel/MW-ST approach to SnO 2 nanoparticles. [128] The decomposition of a SnCl 2 ·H 2 O/citric acid complex into carbon-containing species may shorten the reaction time and prevent particle agglomeration ( Figure 6).…”

“…[122][123][124][125][126][127][128][129][130] One of them demonstrates how the technical potential of MW-ST approaches can be explored through the construction of special microwave ovens that induce higher field strengths within the samples than the commercially available models. [124] As a result, the reaction temperatures are reached very quickly, thereby reducing the reaction times to only 60 seconds. The resulting SnO 2 nanoparticles are around 5 nm in diameter and their high BET surfaces (up to 191 m 2 g À1 ) makes them promising for gassensor applications.…”

Oxide nanomaterials are indispensable for nanotechnological innovations, because they combine an infinite variety of structural motifs and properties with manifold morphological features. Given that new oxide materials are almost reported on a daily basis, considerable synthetic and technological work remains to be done to fully exploit this ever increasing family of compounds for innovative nano-applications. This calls for reliable and scalable preparative approaches to oxide nanomaterials and their development remains a challenge for many complex nanostructured oxides. Oxide nanomaterials with special physicochemical features and unusual morphologies are still difficult to access by classic synthetic pathways. The limitless options for creating nano-oxide building blocks open up new technological perspectives with the potential to revolutionize areas ranging from data processing to biocatalysis. Oxide nanotechnology of the 21st century thus needs a strong interplay of preparative creativity, analytical skills, and new ideas for synergistic implementations.

“…These defects bring on additional electronic states in the band gap, which can mix with the intrinsic states to a substantial extent and which may influence the spacing of the energy levels and the optical properties of nanopowders. A variety of methods were used to prepare SnO 2 nanostructures, such as hydrothermal method, polymeric and organometallic precursor synthesis, soncation procedure, microwave synthesis and surfactant-mediated method [8][9][10][11][12][13][14][15][16][17][18] . Zinc is a quite active element.…”

Zinc doped Tin oxide (SnO 2 ) nanoparticles were prepared by co-precipitation method. The average crystallite size of pure and Zn-doped SnO 2 nanoparticles was calculated from the X-ray diffraction (XRD) pattern. The FT-IR spectrum indicated the strong presence of SnO 2 nanoparticles. The morphology and the particle size were studied using the scanning electron microscope (SEM) and transmission electron microscope (TEM). The particle size of the Zn-doped SnO 2 nanoparticles was also analyzed, using the Dynamic Light Scattering (DLS) experiment. The optical properties were studied by the UV-Visible absorption spectrum. The dielectric properties of Zn-doped SnO 2 nanoparticles were studied at different frequencies and temperatures. The ac conductivity of Zn-doped SnO 2 nanoparticles was also studied.

[128] Die Zersetzung eines SnCl 2 ·H 2 O/Zitronensäure-Komplexes in kohlenstoffhaltige Spezies ist an der Verkürzung der Reaktionsdauer beteiligt und verhindert die Agglomeration der entstehenden Partikel (Abbildung 6).…”

Oxidische Nanomaterialien verbinden eine einzigartige und unerschöpfliche Vielfalt struktureller Motive und Eigenschaften mit einer großen Bandbreite morphologischer Variationen – dies macht sie unverzichtbar für nanotechnologische Innovationen. Die Familie der Oxidmaterialien ist in einem stetigen Wachstum begriffen, und somit liegt eine beträchtliche präparative und technologische Arbeit vor uns, um diese Fülle von Komponenten für neuartige Anwendungen auf der Nanoskala zu erschließen. Dies erfordert die Entwicklung zuverlässiger und skalierbarer Präparationsstrategien, die aber besonders für nanostrukturierte Oxide mit komplexer Zusammensetzung eine Herausforderung sind. Mit ihrem anspruchsvollen physikochemischen Hintergrund eröffnen die bislang eingeführten Methoden den Weg zu nanoskaligen Oxiden verschiedenartiger Morphologie, die auf konventionelle Weise nur schwer erhältlich sind. Die vielfältigen modularen Optionen nanoskaliger Oxide als neue Bausteine können revolutionäre Entwicklungen vorantreiben, von der Datenverarbeitung bis hin zur Biokatalyse. Um diese Wechselwirkungen entsprechend zu nutzen, bedarf die Oxid‐Nanotechnologie des 21. Jahrhunderts einer starken Kombination aus präparativer Kreativität, analytischen Instrumentarien und neuen Anwendungsideen.
