Abstract—In this Letter, we demonstrate for the first time that 7,7,8,8-tetracyanoquinodimethane microsheets
(TCNQMSs) can effectively catalyze the reduction of H₂O₂ because TCNQ is a strong electron acceptor, TCN-
QMSs modified glass carbon electrode (GCE) is prepared by a simple casting method. This H₂O₂ 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 M at a signal-to-noise ratio of 3. Our present study is
important because it provides us a new structure for H₂O₂ detection application.
