Pathway for hydrogen peroxide decomposition on PE surface. (a) Scheme of two steps of reaction, formation of an intermediate hydrogen trioxide from two H₂O₂ molecules and its hydrolysis in O₂ and H₂O. (b) Starting structure of modelled reaction, including two molecules of hydrogen peroxide, a PE surface, and solvent molecules, forming a hydrogen-bond network. Atoms which participate in the reaction are labelled; dotted lines represent hydrogen bonds.
