Nickel Hydroxide Nanopowder (Ni(OH)2)

Nickel hydroxide nanopowder (Ni(OH)₂) is an advanced material with chemical and electroactive properties that is directly used in various industries. This nanopowder with a particle size of less than one hundred nanometers and a light green appearance is an electroactive and is converted to Ni(III). It is also known as a key material in the production of electrodes for nickel-cadmium and nickel metal hydride batteries due to its unique properties. It is also used in the manufacture of electrochemical sensors, photocatalysts and supercapacitors. Its chemical stability and high performance in alkaline environments have made nickel hydroxide nanopowder ideal options in green technologies and environmental applications. These nanoparticles are an inorganic compound with the formula Ni(OH)2. It is a lime-green solid that dissolves in ammonia and amines and is vulnerable to acids.
