“…3 Cu formally exists in 3+ state only in few compounds like ACuO 2 (A ¼ Na, K) and LaCuO 3 and in superconducting cuprates, as mixed valent Cu 2+ /Cu 3+ or as [Cu-O] + . [4][5][6] The highest T c of 164 K is held by Hg-Cu oxides under high pressure. 7 Ag with its similarity to Hg in its chemistry and coordination can be a possible substitute for Hg in Hg cuprates.…”

We report a single step synthesis of AgCuO 2 within minutes resulting in a polycrystalline, single phase product crystallizing in a monoclinic system. Chemical composition analysis has confirmed the stoichiometry of the product with oxygen in slight excess ($0.1). Growth of this oxide involved cuboidal nanoparticles in the initial stages and needle-like microstructures in the final one, as shown by scanning electron microscopy. The novelty of the method lies in the stabilization of Cu in the 3+ state under ambient conditions in a rapid aqueous process.

“…[24][25][26][27] Using molten hydroxides as a solvent allows for product formation at significantly lower temperatures compared with those required for direct reaction of solid reactants. In 2006, Liu et al 28 improved this method for preparation of complex oxides nanostructures in consideration of the eutectic point of composite hydroxides and reduced the reaction temperature to ∼200 C. They named the method as a composite-hydroxides-mediated (CHM) method and prepared various composite oxides nanostructures by this method.…”

PbTe nanocrystals were prepared by a modified molten composite-hydroxides method at 180 degrees C for different times, using Pb(NO3)2 and TeO2 as starting materials and KBH4 as a reductant. The nanocrystal structure and morphologies of the synthesized products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and high resolution TEM (HRTEM), respectively. The results showed that the reaction time has a significant influence on the size and shape of the as-prepared PbTe nanocrystals. As the reaction time increased, the as-prepared products were eventually transformed from nanomaterials (nanocubes, nanorods, and nanosheets) to microcrystals with different morphologies (microcubes, mciroprisms, and microplates). The formation mechanism of the PbTe was proposed, and a one-dimensional oriented attachment growth process combined with two-dimensional oriented attachment growth process was suggested for the growth of nanorods and nanosheets.
