Abstract
Chemical species formed by reactions of tungsten metal, carbide, and nitride with hydrogen peroxide were characterized by multinuclear nuclear magnetic resonance and Raman spectroscopy and gas chromatography. The results not only showed formation of previously known tetraperoxoditungstate, but also strongly suggested formation of diperoxomonotungstate, its protonated form, monoperoxomonotungstate, and diperoxoditungstate. Carbon in tungsten carbide was only oxidized, and oxalate ion, carbon monoxide, and carbon dioxide were produced. On the other hand, both oxidation and hydrolysis of nitrogen were observed for tungsten nitride. It was suggested that the difference of reactivity was explained by the ionicity of tungsten-heteroatom bond.
