Nickel Oxide

Nickel oxide is an important transition metal oxide with the chemical formula NiO. Owing to its unique electrochemical, magnetic, and catalytic properties, it is widely used in batteries, electronics, catalysis, ceramics, and other fields. Nickel(III) oxide, a higher valence oxide of nickel (Ni³⁺) with the chemical formula Ni₂O₃, possesses special application value in areas such as catalysis and energy storage due to its distinct oxidative behavior and instability.
