Abstract
The nature of the catalytically active components is studied in the steady-state decomposition of hydrogen peroxide in alkali media in the presence of an Fe2O3 suspension at 25°C in an intensively shaken reactor. It was found that a hydroxide colloid formed by the mechanical abrasion of the solid catalyst in an aqueous solution shows noticeable catalytic activity together with the initial solid-phase catalyst. As a result, the rate of the catalytic reaction becomes nonlinear with respect to the overall catalyst concentration.
