Abstract

Herein, we report that -MnO2 thin films wet-chemically deposited on electro-conductive substrates exhibited good sensing abilities toward hydrogen peroxide and glucose without the assistance of immobilized enzymes, as well as the excellent supercapacitic performance described in our previous paper. High-sensitivity values of 380mA/(M·cm2) (H2O2) and 300mA/(M·cm2) (glucose) were attained with low detection limits of 0.7-mol/dm3 (H2O2) and 0.6-mol/dm3 (glucose). The good sensitivities and low detection limits were attributed to the large surface area of accumulated MnO2 nanosheets and their firm adhesion to the substrates. The method presented herein can be used for facile film deposition with good controllability and reproducibility.
