چکیده:

Carbon paste electrode modified with aminated MCM-41 was prepared and used for immobilization of
K3[Fe(CN)6] in acidic medium, and then electrochemical behavior of modified electrode containing
ferricyanide was studied in detail, including pH-dependence and scan rate effect. The electrode reactions
showed a surface-controlled process at the scan rate range from 5 to 60 mV s-1. Also the electrocatalytic
behavior of modified electrode toward the reduction of H2O2 is reported and the effect of pH on catalytic
peak current was discussed. It has been demonstrated that ferricyanide immobilized on the aminated MCM-
41 is a stable catalyst for the electrocatalytic reduction of H2O2.
