WebHighly uniform Cu2S nanocrystals with controllable sizes and shapes (circular and elongated) have been synthesized through a novel water−oil interface confined reaction. They can self-assemble into highly ordered multilayer superlattices. By controlling the size and shape of building block nanocrystals, the packing symmetry of the superlattice can … WebThe dissolved copper was reduced to copper metal and obtained by filtration. ... elemental compositions. Examples of such compositions occur as chalcopyrite (CuFeS2), bornite (Cu5FeS4), chalcocite (Cu2S), covellite (CuS), cuprite oxide (Cu2O), and malachite (Cu2CO3(OH)2) among many other minerals (Greenwood & Earnshaw, 1997).

WebKeywords: Copper sulfide; Covellite; Aqueous; Low temperature; Corrosion 1. Introduction The copper sulfide system has been studied extensively ow-ing to its importance in the fields of mineralogy, geology, and corrosion science. Copper sulfides exist in a wide variety of compositions, ranging from copper-rich chalcocite (Cu 2S) to Cu2S can be prepared by treating copper with sulfur or H2S. The rate depends on the particle size and temperature. Cu2S reacts with oxygen to form SO2: 2 Cu2S + 3 O2 → 2 Cu2O + 2 SO2 The production of copper from chalcocite is a typical process in extracting the metal from ores. Usually, the conversion involves roasting, to give Cu2O and sulfur dioxide: smallseotool free plagiarism checker
