Abstract
The catalytic activity of the colloidal catalyst based on iron(III) hydroxide was studied in the decomposition of H2O2 in a neutral medium (pH 6.7). A colloidal micellar solution of iron(III) hydroxide after preparation was kept at 19–20 °С for 2 or 20 h without additives or with C2H5OH additives. The decomposition of H2O2 under the action of the colloidal catalyst (20 h) proceeds via the first-order reaction with the decay rate constant kd = 1.26•10–4 s–1, whereas the decay rate of the first-order reaction is kd = 0.77•10–4 s–1 for the colloidal catalyst (2 h) prepared in the presence of C2H5OH.
