Enzymatic and electrochemical reactions of catalase immobilized on carbon materials.
It has been shown that catalase immobilized on graphite and soot undergoes an oxidation reduction transformation. Some results on the effect of the potential sweep rate, temperature and pH on this transformation are presented. On the basis of the relationship established, it has been proved that the redox transformation is related to the iron in the heme of the active center of the enzyme and takes place with a transfer of one electron.
