Electrochemical characterizations of Iron oxide/Au core/sell nano particles by embedding of them on GCE/MWCNTs electrode surface

In this work a novel method for electrochemical characterization of Iron oxide/Au core/shell nano particles was reported. Co-precipitation method was used for synthesizing Iron oxide corefollowing by citrate reduction for preparing Au shell. A glassy carbon electrode was modified by dropping a suspension of oxidized multi walled carbon nano tubes on its surface. After drying of CNT layer, some dispersion of Iron oxide/Au core/shell nano particles was embedded on CNTlayer. The electrochemical studies using CV technique showed very sharp picks related to Au shell. The absence of Iron oxide peaks verified full coating of them by Au shell.
