peroxoozone

Peroxozone is a highly unstable and potent oxidizing agent composed of a peroxide linked to an ozonide group. Its chemical formula is O3O(OO)OH. This compound is a member of the ozonide family and is formed in the presence of ozone (O3) and peroxy radicals.

Peroxozone is not a naturally occurring compound in the environment, but rather a product of certain chemical reactions that involve ozone. It has been observed in some atmospheric and aqueous systems, particularly in areas where ozone and hydrogen peroxide coexist. In the stratosphere, peroxozone can play a role in the degradation of ozone depleting substances (ODS).

Peroxozone is highly reactive and can facilitate the oxidation of organic compounds, including volatile organic compounds (VOCs) and particulate matter. Its reactivity is attributed to the presence of ozone, which is a strong oxidant. In addition, peroxozone can participate in various redox reactions, influencing the atmospheric budgets of certain gases.

The formation of peroxozone is often linked to the presence of peroxy radicals, which are high-energy intermediates involved in atmospheric chemistry. Its decomposition products include peroxynitric acid and other reactive species. Studies have shown that peroxozone can have both positive and negative effects on atmospheric chemistry, depending on the specific conditions and pathways.

Given its reactivity and short lifetime, peroxozone poses challenges for investigation and quantification. However, research has contributed to a better understanding of its role in atmospheric chemistry, and its significance is being explored in various scientific and environmental contexts.
