Journal ArticleDOI
Oriented attachment and mesocrystals: Non-classical crystallization mechanisms based on nanoparticle assembly
TL;DR: A non-exhaustive literature survey on particle based crystallization pathways leading to single crystals via mesoscopic transformation with a focus on recent examples and studies, which are dedicated to a mechanistic understanding.
Journal ArticleDOI
Nonaqueous Sol–Gel Routes to Metal Oxide Nanoparticles
TL;DR: The organic components strongly influence the composition, size, shape, and surface properties of the inorganic product, underlining the demand to understand the role of the organic species at all stages of these processes for the development of a rational synthesis strategy for inorganic nanomaterials.
Journal ArticleDOI
Organic reaction pathways in the nonaqueous synthesis of metal oxide nanoparticles.
TL;DR: General mechanistic principles for aqueous and nonaqueous sol-gel processes are presented, followed by the discussion of reaction pathways relevant for nanoparticle formation in organic solvents.
Journal ArticleDOI
Surfactant-free nonaqueous synthesis of metal oxide nanostructures.
Nicola Pinna,Markus Niederberger +1 more
TL;DR: Surfactant-free processes, which have become a valuable alternative to surfactant-assisted as well as to traditional aqueous sol-gel chemistry routes, are discussed.
Journal ArticleDOI
Template-free synthesis and assembly of single-crystalline tungsten oxide nanowires and their gas-sensing properties.
TL;DR: A nonaqueous approach that involves the reaction of tungsten isopropoxide with benzyl alcohol leads to tungstein oxide nanowire bundles without the use of any additional structure-directing templates, which show a high sensitivity to NO2.

A New Nonhydrolytic Single-Precursor Approach to Surfactant-Capped Nanocrystals of Transition Metal Oxides
TL;DR: In this article, a non-hydrolytic single-precursor approach to the synthesis of dispersable nanocrystals of transition metal oxides is presented, which is of considerable interest to us.
Journal ArticleDOI
Surfactant-assisted elimination of a high energy facet as a means of controlling the shapes of TiO2 nanocrystals.
TL;DR: The surfactant-mediated shape evolution of titanium dioxide anatase nanocrystals in nonaqueous media was studied and the modulation of surface energies of the different crystallographic faces through the use of a surface selective surfactants is the key parameter for the shape control.
Journal ArticleDOI
Nonhydrolytic Sol−Gel Routes to Oxides
TL;DR: In this paper, the chemistry of various non-hydrolytic sol−gel processes including hydroxylation in nonaqueous systems and aprotic condensation reactions are surveyed.
Journal ArticleDOI
Benzyl alcohol and titanium tetrachloride - A versatile reaction system for the nonaqueous and low-temperature preparation of crystalline and luminescent titania nanoparticles
TL;DR: The reaction between TiCl4 and benzyl alcohol is a simple and nonaqueous procedure for the synthesis of highly crystalline titania nanoparticles at temperatures as low as 40 °C as mentioned in this paper.
Journal ArticleDOI
Multigram scale synthesis and characterization of monodisperse tetragonal zirconia nanocrystals.
TL;DR: In this article, a non-hydrolytic sol−gel reaction between zirconium(IV) isopropoxide and ZrO2 chloride at 340 °C generated 4 nm sized Zirconia nanoparticles with an average size of 2.9 nm.
