H2O2gasplasma

H2O2gasplasma refers to a non-thermal plasma generated from hydrogen peroxide vapor. This type of plasma is characterized by its low operating temperature, making it suitable for treating temperature-sensitive materials. The plasma state involves the ionization of gases, creating a collection of charged particles, free radicals, and energetic species. In the case of H2O2gasplasma, the primary reactive species include hydroxyl radicals (OH•), atomic oxygen (O•), and ozone (O3), along with excited molecules of hydrogen peroxide. These reactive species are highly efficient at initiating chemical reactions.

The generation of H2O2gasplasma typically involves passing hydrogen peroxide vapor through an electrical discharge, such as a dielectric barrier discharge or a corona discharge. The low pressure or atmospheric pressure conditions under which it can operate are advantageous for various applications. Its key properties include strong oxidizing capabilities and the ability to sterilize and decontaminate surfaces.

Applications of H2O2gasplasma are found in areas like surface modification of polymers, sterilization of medical devices and food packaging, and in advanced oxidation processes for wastewater treatment. The low temperature ensures minimal damage to the treated substrates, while the potent reactive species effectively break down organic contaminants and microbial cells. Research continues to explore its potential in fields such as medicine, environmental remediation, and materials science.
