In chemistry, peroxocarbonate is a divalent anion with formula CO42−. It is an oxocarbon anion that consists solely of carbon and oxygen. It would be the anion of an hypothetical peroxocarbonic acid HO–CO–O–OH.〔 E. H. Riesenfeld, B. Reinhold (1909), ''Die Existenz echter Percarbonate und ihre Unterscheidung von Carbonaten mit Krystall-Wasserstoffsuperoxyd''. Berichte der deutschen chemischen Gesellschaft, 42(4), 4377–4383, . 〕〔 E. H. Riesenfeld, W. Mau (1911): Isomere Percarbonate. Berichte der deutschen chemischen Gesellschaft, 44(3), 3595–3605, 〕 The peroxocarbonate anion is formed, together with peroxodicarbonate C2O62−, at the negative electrode during electrolysis of molten lithium carbonate.〔 Li-Jiang Chen, Chang-Jian Lin, Juan Zuo, Ling-Chun Song, and Chao-Ming Huang (2004), ''First Spectroscopic Observation of Peroxocarbonate/ Peroxodicarbonate in MoltenCarbonate''. J. Physical Chemistry B, volume 108, 7553-7556 〕 Lithium peroxocarbonate can be produced also by combining carbon dioxide CO2 with lithium hydroxide in concentrated hydrogen peroxide H2O2 at −10 °C.〔 T.
