Nickel(II) Selenide Powder Description:
Nickel(II) Selenide (NiSe) Powder is a dark gray to black inorganic compound composed of nickel and selenium in a 1:1 stoichiometric ratio. It is a transition metal chalcogenide with a hexagonal crystal structure, known for its semiconducting properties and catalytic activity. NiSe powder exhibits excellent electrical conductivity, thermal stability, and chemical resistance, making it suitable for applications in electrocatalysis (e.g., hydrogen evolution reaction), energy storage (e.g., batteries and supercapacitors), and photovoltaic devices. Its fine particle size and high surface area enhance its performance in these applications. NiSe is typically synthesized through solid-state reactions, hydrothermal methods, or chemical vapor deposition (CVD). Proper handling is required due to its reactivity and potential toxicity.
