Used as a catalyst in hydrogenation and hydrodesulfurization processes, particularly in the petrochemical industry. It plays a role in producing clean fuels by removing sulfur from crude oil derivatives. Also employed in electroplating baths to deposit nickel-sulfide coatings, which offer good corrosion and wear resistance. In electronics, it serves as a component in semiconductor materials and thin-film coatings due to its electrical and optical properties. Additionally, it finds use in research for synthesizing nickel-based nanomaterials and advanced catalysts.
