“…[45] Under the acidic conditions (low pH value), reactions in Equations (9-12) are suppressed and the formed Cu + ions react with Se 2-ions to form Cu2Se precipitates. [46] In the basic solution (i.e. OH -or NaBH4 is excess), Cu2O is formed through Equations (9-10).…”

“…[45][46][47][48] In this process, the reduction of Cu 2+ by NaBH4 includes several reactions [Equations (5-14)], which are strongly dependent on their ratios and the pH of solution. According to the literature, [45][46][47][48] NaBH4 itself can be hydrolyzed to release H2…”

, S. Xue. (2015). Robust scalable synthesis of surfactant-free thermoelectric metal chalcogenide nanostructures. Nano Energy, Robust scalable synthesis of surfactant-free thermoelectric metal chalcogenide nanostructures AbstractA robust low-cost ambient aqueous method for the scalable synthesis of surfactant-free nanostructured metal chalcogenides (MaXb, M=Cu, Ag, Sn, Pb, and Bi; X=S, Se, and Te; a=1 or 2; and b=1 or 3) is developed in this work. The effects of reaction parameters, such as precursor concentration, ratio of precursors, and amount of reducing agent, on the composition, size, and shape of the resultant nanostructures have been comprehensively investigated. This environmentally friendly approach is capable of producing metal chalcogenide nanostructures in a one-pot reaction on a large scale, which were investigated for their thermoelectric properties towards conversion of waste heat into electricity. The results demonstrate that the thermoelectric properties of these metal chalcogenide nanostructures are strongly dependent on the types of metal chalcogenides, and their figure of merits are comparable with previously reported figures for their bulk or nanostructured counterparts.

Abstract. Using sodium dodecyl sulfate/isoamyl alcohol/n-heptane/water as reaction medium, copper chloride as precursor, Sodium boron hydride as reducing agent, aniline hydrochloride as monomer, copper/polyaniline nanocomposite was prepared by the method of inverse microemulsion polymerization. The nano-composite was characterized by XDS, FTIR and TEM. The result of XDS confirmed that the copper/polyaniline composite contained the main elements of copper, carbon, nitrogen and had no oxygen. It was showed that the polyaniline could effectively prevent the nano copper from being oxidized. FTIR spectra of the material inferred polyaniline was successfully obtained by the polymerization. TEM image showed nanocomposite was core-shell structure, and its average particle size was about 30nm.

“…To counter oxidation, the synthesis/deposition of copper nanoparticles used harsh reducing agents of hydrazine 164 and sodium borohydride 78,106 . Additives such as PVP 85 or CTAB 165 can increase the solution stability and control the particle size of the copper nanoparticles, but there is an inherent tradeoff when adding large molecules and polymers on the resulting porosity/conductivity of IPL processed films.…”
