· H4 O10 Ni2 Se2

H₄O₁₀Ni₂Se₂ is a nickel selenide hydroxide compound, a layered semiconductor material combining nickel, selenium, and hydroxyl groups in a mixed-valence structure. This is primarily a research-phase material studied for its potential in electrochemistry and energy storage applications, particularly as an active material for water-splitting catalysts and battery electrode components. The material is notable within the nickel selenide family for its structural stability and electronic properties that make it attractive for sustainable energy conversion and storage, though it remains largely in academic development rather than established industrial production.
