A Novel Solution Route for Preparing Indium Nanoparticles

Abstract

In this paper, we report a novel preparation method for indium nanoparticles from bulk indium that involves surface oxidation and dispersion of indium droplets. Indium nanoparticles of well-defined size are obtained by dispersing melt indium in an appropriate solvent. Powder X-ray diffraction and transmission electron microscopy show the formation of indium nanoparticles possessing the same crystal structure as bulk indium and an average particle diameter of 30 nm. The samples display a strong surface plasmon absorption band at 240 nm, which indicates that the sample is metal indium and the particle size is less than 50 nm. Thermal analysis reveals that the samples contain at least 55 wt % organic solvent. Tribological results show that indium nanoparticles have good antiwear properties.

Hydrothermal synthesis of CaSnO 3 cubes

“…Inorganic materials of uniform shape and size are of fundamental interest and technological importance due to their unique size-and shape-dependent properties [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. During the past decade, much efforts has been tried to fine-tune the shape and size of inorganic materials and cube is one of the focus [19][20][21][22][23][24][25][26][27][28][29][30][31][32]. Although considerable strategies have been developed for growing cubes of transition metals [20,25,33], transition metal oxides [21,24,29], halides [22], chalcogenides [28] and so on, there is few examples on ternary complex oxides.…”

Here we present a facile hydrothermal method to the largescale synthesis of perovskite structured CaSnO 3 cubes in the presence of polyvinylpyrrolidone (PVP) surfactant and size-control of these cubes has been achieved by varying the surfactant concentration.…”

Synthesis and characterization of In2S3 nanoparticles

“…In previous papers, we have successfully produced metal nanoparticles by solution dispersion route in which the melting metal can be dispersed into nanosized droplets and converted into metal nanoparticles when the temperature is reduced to room temperature [15,16]. In this paper, we report a modified solution dispersion route to prepare In 2 S 3 nanoparticles through one-step elemental reactions in paraffin oil.…”

Electrochemical Synthesis of Indium(0) Nanoparticles in Haloindate(III) Ionic Liquids

“…[4] However, only few papers describe the synthesis of indium(0) nanoparticles. [5] The published physical methods require either specialised techniques (e.g., sonication, [6] laser ablation, [7] sputter deposition, [8] or solvated metal atom dispersion with subsequent digestive ripening [1] ) or at least high temperatures (dispersing molten indium in paraffin oil, > 180 8C [9] ). The chemical methods involve reduction by strong reducing agents, for example, metallic sodium [10] or sodium tetrahydroborate(III), [11] and there have only been a few reported cases of catalysis with indium(0) nanoparticles.…”
