·As a promising and alternative solar absorber material the copper zinc tin sulfide compound Cu 2 ZnSnS 4 has been drawing attention in recent years for the production of cheap thin film solar cells owing to the high natural abundance and non toxicity of all the constituents a tunable direct band gap energy and a large
·This review captures the synthesis assembly properties and applications of copper chalcogenide NCs which have achieved significant research interest in the last decade due to their compositional and structural versatility The outstanding functional properties of these materials stems from the relationship between their band structure
·An understanding of the fundamentals of the reaction between CuO with trace amounts of H2S to form CuS products is critical for the optimal utilization of this process in sulfur removal applications Unfortunately CuS is a complex material featuring various Cu2 xS compounds with 0 ≤ x ≤ 1 distorted crystal phases and varying
·The Formation of Ionic Compounds Binary ionic compounds are composed of just two elements a metal which forms the cations and a nonmetal which forms the anions For example NaCl is a binary ionic compound We can think about the formation of such compounds in terms of the periodic properties of the elements
In the first compound the iron ion has a 2 charge because there are two Cl − ions in the formula 1− charge on each chloride ion In the second compound the iron ion has a 3 charge as indicated by the three Cl − ions in the formula These are two different compounds that need two different names
Nomenclature a collection of rules for naming things is important in science and in many other module describes an approach that is used to name simple ionic and molecular compounds such as NaCl CaCO 3 and N 2 O simplest of these are binary compounds those containing only two elements but we will also consider how to name

The cyclic voltammogram of M individual tin chloride is shown in Figure 2 The scan begins from the left hand side of the current/voltage plot
· Anilite Cu 7 S 4 Several polymorphs of copper sulfide of general formula Cu x S 1 ≤ x ≤ 2 have been characterized In these structures the location of Cu atoms in the close packed S lattice is not well identified and their positions change as a function of the composition x In a copper rich environment the experimentally identified
Ionic compounds generally form from metals and nonmetals Compounds that do not contain ions but instead consist of atoms bonded tightly together in molecules uncharged groups of atoms that behave as a single unit are called covalent compounds Covalent compounds usually form from two or more nonmetals
·The power factor PF of copper sulfide based composites as a function of temperature is shown in Fig 4 f The PF is improved at low to mid temperatures for copper sulfide with an increasing boron content which slightly reduces at 773 K since partial carriers tend to be distributed gently and contribute less to the resonance level [59]
·Copper based adsorbents such as Cu I Y zeolite Cu II Y zeolite CuCl/MCM 41 MCM 41 stands for Mobil Composition of Matter No 41 Hydrogen sulfide and dimethyl sulfide DMS were the main sulfur compounds The results showed that hydrogen sulfide is adsorbed more strongly than DMS showing adsorption energies
·Uses of Copper Compounds Copper Sulphate Copper sulphate blue stone blue vitriol are all common names for pentahydrated cupric sulphate Cu S04 5 H20 which is the best known and the most widely used of the copper salts By heating copper sulphide ores to produce copper oxide which is then treated with sulphuric acid to form
·The Allanore Group researchers successfully identified other sulfide compounds that when added to copper sulfide change the behavior of the melt so that the ions rather than electrons become the primary charge carriers through the system and thus enable the desired chemical reactions Technically speaking the additives raise the
·Recently copper sulfide CuS and copper selenide CuSe compounds have garnered interest as thermoelectric generators because their extraordinarily low thermal conductivities enable highly
·The autoclave was heated to 180 °C for 16 h and then cooled down to room temperature naturally The product was collected carefully by centrifuging and dried at 60 °C for 10 h and then washed with distilled water and anhydrous ethanol This process was repeated several times and then the copper sulfide compound powders were obtained
Replace immutable groups in compounds to avoid ambiguity For example C6H5C2H5 O2 = C6H5OH CO2 H2O will not be balanced but XC2H5 O2 = XOH CO2 H2O will Compound states [like s aq or g ] are not required You can
·Compound Name Compound Formula K sp; Aluminum phosphate AlPO 4 × 10 −21 Barium bromate Copper I bromide CuBr × 10 −9 Copper I chloride CuCl 1 CuC 2 O 4 × 10 −10 Copper II phosphate Cu 3 PO 4 2 × 10 −37 Copper II sulfide CuS × 10 −36 Europium III hydroxide Eu OH 3 ×
·In recent decades copper based quaternary chalcogenides I 2 II IV VI 4 have emerged as a promising multifunctional material for various transition and alkaline earth metals are mostly used in place of X in the Cu 2 XSnS 4 structure In 1974 Schafer et al [5] first reported the X ray diffraction XRD data of about 42
Compounds Composed of Two Elements When two nonmetallic elements form a molecular compound several combination ratios are often possible For example carbon and oxygen can form the compounds CO and CO these are different substances with different properties they cannot both have the same name they cannot both be called carbon
·Copper sulfides were identified as a promising TE material since 1827 [18 20] With low j and high TE performance copper sulfides attract extensive research interest [21 27] Currently the field of copper sulfides is mainly focusing on the reduction of j by designing intrinsically low dimensional crystalline structures and on
