A simple hydrothermal route to nanocrystalline CuS

Mild hydrothermal synthesis of hexagonal CuS nanoplates

“…However, plate-like CuS nanostructures are of particular interest because the nanoplates are promising building blocks for nanodevices with controlled crystal orientation by a bottom-up route owing to their anisotropic structures [17,18]. Recently, many efforts have been devoted to the synthesis of CuS nanoplates [19][20][21][22][23][24][25][26]. Lou et al [19] have prepared CuS triangular nanoplates by means of the solvothermal process at 140 1C.…”

“…Ghezelbash and Korgel [25] have obtained CuS nanodisks by means of the solution-phase-arrested precipitation of copper sulfide nanocrystals at 182 1C. Zhang et al [26] have reported the preparation of CuS nanoplates under hydrothermal conditions at 150-170 1C. Despite all these success, to the best of our knowledge, there is no report on the preparation of monodisperse hexagonal CuS nanoplates with controlled plane size and thickness up to now.…”

“…Alternatively, [Cu(S 2 O 3 )(H 2 O)2 ] may undergo an overall conversion in the acidic media to form CuS[26]. The possible reactions for the formation of CuS were described as follows:…”

A micro-interface route to CuS superstructure composed of intersectional nanoplates

“…Tang et al [31] synthesized CuS nanoplate with plane sizes ranging from 200 to 500 nm in homogeneous solutions via a hydrothermal route, in which CuO was the Cu source and Na 2 S 2 O 3 Á 5H 2 O was the S source . Wang et al [5] synthesized CuS nanoplate with average size of about 20-40 nm in homogeneous solutions via a sonochemical synthesis.…”

Template free-solvothermaly synthesized copper selenide (CuSe, Cu2−xSe, β-Cu2Se and Cu2Se) hexagonal nanoplates from different precursors at low temperature

“…Recently, much effort has been dedicated to the synthesis of copper sulfide (CuS) nanoplates with different methods, e.g. solvothermal process, hydrothermal micro-emulsions method, sono-chemical synthesis route, vacuum chemical vapor reaction method, improved solvothermal method and by solution-phase-arrested precipitation method in the range 100-200 1C using different sources [36][37][38][39][40][41][42][43]. Despite all these successes, to the best of our knowledge, there is no report on the preparation of hexagonal CuSe nanoplates up to now.…”
