Antimony doped tin oxide (ATO) conductive nano-particles are synthesised by alkoxide hydrolysis method using SnCl4•5H2O and SbCl3 as raw materials. The optimum parameters are determined as: Sb3+ doped molar concentration 15%, reaction temperature 60°C and roasting temperature 600°C. Under optimum conditions, the synthesised nano-particles are characterized by means of X-ray diffraction (XRD) and transmission electron microscope (TEM). XRD results show that all Sb ions came into the SnO2 lattice to substitute Sn ions. The image of TEM shows the ATO conductive nano-particles average size is 5 nm. Volume resistivity lowest value of ATO nano-particles is 141 Ω•cm.

In present study, the synthesis and characterization of a novel polypyrrole (PPy)/tin oxide (SnO2)/MWCNT nanocomposite along with pristine polypyrrole is reported. These materials have been studied for their structural and morphological properties by FT-IR spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) techniques. PPy/SnO2/MWCNT nanocomposite has been converted into a pellet-shaped sensor, and its ammonia sensing studies were carried out by calculating the variation in the DC electrical conductivity at different concentration of ammonia ranging from 10 to 1500 ppm. The sensing response of the sensor was determined at 1500, 1000, 500, 200, 100 and 10 ppm and found to be 70.4, 66.1, 62.2, 55.4, 50.8 and 39.7%, respectively The sensor showed a complete reversibility at lower concentrations along with excellent selectivity and stability. Finally, a sensing mechanism was also proposed involving polarons (charge carriers) of polypyrrole and lone pairs of ammonia molecules

A simple method for preparing nanoscale copper ferrite particles with narrow distribution and uniform size was developed by auto-combusting the precursor using copper nitrate, iron nitrate, and malic acid as raw materials. The constituents and the thermal decomposition process of the precursor were studied by Fourier transform infrared (FT-IR), thermogravimetry-differental thermal analysis (TG-DTA) and X-ray diffraction (XRD). The results showed that the carboxyl and nitrate ion take part in the reaction during the auto-combustion process. The precursor decomposed completely at about 199 °C, to yield single phase product. Transmission electron microscopy (TEM) indicated that the average size of the as-burnt sample was about 90 nm.

LiFePO4/C nano-particles were synthesized by microwave assisted carbothermal reduction method, using LiOH•H2O,FePO4•2H2O and sucrose as raw materials. LiFePO4/C samples with different particle sizes were prepared by heating at different temperatures in an industrial microwave oven. The samples were characterized by X-ray diffraction, field emission scanning electron microscopy, laser particle sizer analysis and electrochemical performance test. The results showed that the average size of samples is about 100 to 300 nm. The first discharge capacity decreased with the increase of temperature. The LiFePO4/C particles prepared at temperature of 700°С for 15 min exhibited the best capacity of 156.9mAh/g at 0.2C rate, and had just ~6% capacity loss after 50th cycles.

In this paper, employing Cu(AC)2•H2O, SnCl2•2H2O and thiourea as raw materials, the composites of graphene/Cu2SnS3 quantum dots (QDs) were prepared simply and quickly using the hydrothermal method. Meanwhile, the separate Cu2SnS3 QDs were also synthesized in the same way. The as-obtained Cu2SnS3 QDs and composites’ phase structures were analyzed and characterized by powder X-ray diffraction (XRD), and the results indicated that the size of the Cu2SnS3 QDs in the composites were less than that of the separate Cu2SnS3 QDs. At the same time, their morphologies were also observed and cross-confirmed by Transmission Electron Microscopy (TEM), and the measurements manifested that Cu2SnS3 QDs were uniformly dispersed on the surface of the graphene, while the separate Cu2SnS3 QDs have obvious glomeration. In addition to this, elemental analysis was also made to verify the existence of Cu2SnS3 on the surface of graphene.
