Noteworthy is that highly chemoselective reactions were achieved in the presence of other functional groups such as halogens, carbon-carbon double bonds and hydroxyl groups.展开更多

The effects of cationic concentrations and numbers of cycle on the properties of CuInS2 film were investigated. The chemical composition, crystalline structure, surface topography, deposited rate, optical and electronic properties of the films were characterized by X-ray diffractrometry (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), ultraviolet-visible spectrometry (UV-Vis) and Hall System. The results show that the crystalline of CuInS2 thin films and the deposition rate have been improved with the increase of cationic concentration, while CuxS segregation phases appear with further increasing cationic concentration. The deposition rate is close to constant as cationic concentration is fixed.CuInS2 thin film derived form lower cationic concentration is uniform, compact and good in adhesion to the substrates. The absorption coefficient of CuInS2 thin films is larger than 104 cm^-1, and the band gap Eg is in the range of 1.30-1.40 eV. The dark resisitivity of the thin film decreases from 50 to 10 Ω·cm and the carrier concentration ranges are over 10^16 cm^-3.展开更多

The selection and preparation of electrolyte in electrorefining indium were investigated, and the effect of component of electrolytic solution on electrolytic refining was also studied. Compared with electrolyte of InCl3-HCl, electrolyte of In2（SO4）3-H2SO4 has higher stability and lower corrosivity, electrolytic solution can be heated at low temperature, and bath is open and simple, which makes operation more convenient. The results show that the voltage can be kept at 0.30.5 V, and the content of indium can exceed 99.999% when the content of indium（Ⅲ） ion and sodium chloride are 80120 g/L. The bench-scale test of electrolysis was carried out, and the product of indium reaches the national standard of 99.999% high purity indium.展开更多

The salient advantages of this method are mild reaction conditions, environmentally benign, high to excellent yields, shorter reaction times, easy operation and no column chromatographic separation.展开更多
