Nickel sulfide (Ni7S6) | NiS | CID 166709 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities ...
Nickel is commonly present in two principal ore types—sulfide or laterite. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt (Co), and often precious metals such as gold (Au) or platinum (Pt), palladium (Pd) and rhodium (Rh) (the platinum group metals or PGMs) …
1. Introduction. Nickel is an important strategic metal produced at over 2 million tonnes annually [1].Approximately 60% of all Ni is consumed in the production of stainless steel [2, 3].Currently, Ni is primarily extracted from two types of ores: laterites and sulfides [[4], [5], [6], [7]].Although sulfide ores account for a smaller fraction of global Ni …
Electrocatalysis for the oxygen evolution reaction (OER) plays an irreplaceable role in numerous green and efficient energy conversion or storage techniques such as water electrolysis, fuel cells, and metal–air batteries. High-performance catalysts are always needed despite the sluggish kinetics of the four electron-transfer OER process. In this …

Supercapacitor technology has become a popular topic as one of the energy storage systems. As a promising anode material, nickel sulfide (Ni 3 S 2) is hindered for energy storage applications by its low conductivity and inability to meet the expected capacity.Introducing impurities and surface defects can modulate its electronic structure …
Water splitting is one of the ideal technologies to meet the ever increasing demands of energy. Many materials have aroused great attention in this field. The family of nickel-based sulfides is one of the examples that possesses interesting properties in water-splitting fields. In this paper, a controllable and simple strategy to synthesize nickel sulfides was …
The platinum-nickel/nickel sulfide heterostructures can deliver a current density of 37.2 mA cm−2 at an overpotential of 70 mV, which is 9.7 times higher than that of commercial Pt/C.
Nickel sulfide ores associated with komatiites in Archean greenstone belts are the most important examples of mag- matic mineralization in volcanic rocks. They contain about 25 percent of the world total identified nickel resource in deposits with ≥0.8 percent Ni, as well as significant amounts of copper and platinum-group elements (PGE).
Abstract. Nickel (Ni) is an important metal in modern infrastructure and technology, with major uses in stainless steel, alloys, electroplating and rechargeable …
Nickel* CATHERINE KLEIN, MAX COSTA, in Handbook on the Toxicology of Metals (Third Edition), 2007. 3.1 Production. Nickel exists as a natural earth element, primarily in sulfide or oxide ores that are mined underground or in open pits. It is the 24th most abundant element on earth, with the greatest deposits of nickel ores in Canada, Siberia, and New …

Sulfide nickel ores serve as an essential raw material for the nickel industry. Representing approximately 40 pct of the global nickel ore reserves, the sulfide nickel ores constitute approximately 30 pct of all the nickel production worldwide.[] Pyrrhotite (Pyrr), pentlandite (Pn), chalcopyrite, pyrite (Py), and gangue are the major …
The raw materials used to synthesize nickel sulfide E-Ms are sulfur powder (S) and NiF. The raw materials are of analytical grade. The Ni-F is washed with HCL (M = 1 mol) by dipping process, then washed many times in distilled water and acetone, after that it is dried with argon flow rate (200 sccm) at room temperature.
Consequently, at best only 46 percent of the world's nickel production—Class 1 nickel—can be used in batteries (Exhibit 2), and a scarcity of sulfide deposits is contributing to a looming shortage of Class …
Nickel Sulphide is one of the important classes of metal sulphides. Nickel sulphide has many phases, some phases are nickel rich and some phases are sulphur rich such as α-NiS, β-NiS, Ni 17 S 6, Ni 3 S 4, NiS 2, Ni 3 S 2, etc. . Out of these phases only two are the most stable phases; one is rhombohedral β-NiS, and hexagonal α-NiS .
