The invention relates to a 2-benzylthio-aniline croconic acid cyanine chemical sensor capable of identifying Hg and a preparation method of the chemical sensor. The preparation method comprises steps as follows: 2-benzylthio-aniline is synthesized from 2-aminothiophenol and benzyl chloride, and a 2-benzylthio-aniline croconic acid cyanine dye compound is synthesized from 2-benzylthio-aniline and croconic acid. The chemical sensor and the preparation method have beneficial effects as follows: the synthetic process is relatively simple, reaction conditions are easy to control, and the prepared 2-benzylthio-aniline croconic acid cyanine dye has excellent optical performance and optical stability. When the 2-benzylthio-aniline croconic acid cyanine dye is used for identifying Hg, colorof a solution also changes besides change of an absorption spectrum, so that the 2-benzylthio-aniline croconic acid cyanine dye has a colorimetric identification function and facilitates detection for Hg. Besides, the 2-benzylthio-aniline croconic acid cyanine dye has good selectivity and anti-interference performance for identification of Hg.

Vesicles self-assembled from an aqueous PEGylated surfactant ionic liquid solution can be applied for stabilizing palladium nanoparticles, which prove to be an efficient catalytic system for chemoselective hydrogen transfer of nitroarenes using hydrazine hydrate as a hydrogen source. The particle sizes of vesicles are decreased with the increase of ionic liquid's concentrations and relatively small particle sizes are beneficial to the reduction. Moreover, the aqueous catalytic system still stays in reactor by simple extraction, and is reused without further treatment.

One-pot and three components C-S bond formation reactions in thioethers and S-aryl-carbamodithioates have been catalyzed by a copper heterogeneous nano-catalyst supported on modified AlPO4 under different reaction conditions. The above-mentioned nano-catalyst has been characterized by various techniques such as SEM, TEM, AFM, XRD, FT-IR, UV–Vis, CV, BET, TGA, ICP and XPS spectrometry and its particle size was estimated to be between 60–110?nm. Finally, the reusability of the catalyst up to ten cycles without any significant leaching is one of the outstanding properties of the catalyst.
