Webb30 jan. 2024 · As a narrow bandgap semiconductor, NiS 2 is promising to be an efficient electrocatalyst towards hydrogen evolution reactions (HER) by regulating the local electronic structure. The mechanism of transition metal doping to improve the electrocatalytic performance of NiS 2 is not comprehensively reported yet. To this end, … Nickel sulfide is any inorganic compound with the formula NiSx. They range in color from bronze (Ni3S2) to black (NiS2). The nickel sulfide with simplest stoichiometry is NiS, also known as the mineral millerite. From the economic perspective, Ni9S8, the mineral pentlandite, is the chief source of mined nickel. Other minerals include heazlewoodite (Ni3S2) and polydymite (Ni3S4). The mineral Vaesite is NiS2. Some nickel sulfides are used commercially as catalysts. Webb25 maj 2009 · NiS is the formula for nickel sulfide. The nickel (II) ion has a 2+ charge and the sulfide ion is 2-.
