|Section2= |Section7= }} Nickel(III) oxide (Ni2O3) has been referred to in the literature, but is not a well characterised compound. The substance black nickel oxide is sometimes described as being Ni2O3; however, the composition quoted by suppliers has a nickel content of around 77% by weight, whereas Ni2O3 would have 70.98% Ni by weight, and may be non-stoichiometric NiO.〔 There are references in the literature to traces of Ni2O3 on nickel surfaces, and as intermediates in nickel oxidation, e.g.〔An oxide of tervalent nickel , P. S. Aggarwal, A. Goswami, J. Phys. Chem.; 1961; 65(11); 2105-2105, 〕〔Chemical vapor deposition of nickel oxide films from Ni(C5H5)2/O2, Jin-Kyu Kang, Shi-Woo Rhee, Thin Solid Films, 391, 1, (2001),57-61, 〕 ==Nickel oxide hydroxide== The related nickel oxide hydroxide (NiOOH) can be prepared by reaction of nickel(II) chloride with sodium hypochlorite; the sodium hypochlorite functions as an oxidizing agent: 4OH− + 2NiCl2 + NaClO ---> Na+ + H2O + 2NiOOH + 5Cl− In one modification〔''An Efficient and Practical System for the Catalytic Oxidation of Alcohols, Aldehydes, and ,-Unsaturated Carboxylic Acids'' Joseph M.
