7,7,8,8-tetracyanoquinodimethane microsheets for hydrogen peroxide reduction

In this Letter, we demonstrate for the first time that 7,7,8,8-tetracyanoquinodimethane microsheets (TCNQMSs) can effectively catalyze the reduction of H 2 O 2 because TCNQ is a strong electron acceptor, TCNQMSs modified glass carbon electrode (GCE) is prepared by a simple casting method. This H 2 O 2 sensor shows a fast amperometric response time of less than 3 s, and the corresponding linear range is estimated to be from 3 to 238 mM ( r = 0.992) and a detection limit of 4.76 μM at a signal-to-noise ratio of 3. Our present study is important because it provides us a new structure for H 2 O 2 detection application.
