| Summary: | To conveniently construct an electrochemical non-enzymatic glucose sensor, Mn.sub.2O.sub.3 porous microsheets are utilized as electrode materials in glucose detection. Mn.sub.2O.sub.3 porous microsheets have been prepared by a facile chemical precipitation procedure. The Mn.sub.2O.sub.3 porous microsheets possess a uniform porous structure, which display a nitrogen adsorption-desorption surface area of 38.6 m.sup.2/g and the average pore diameter of 16.0 nm. The pores on the Mn.sub.2O.sub.3 porous microsheets afford large specific surface area. Electrochemical tests reveal that the Mn.sub.2O.sub.3 porous microsheets electrode possesses a remarkable capability in glucose detection. Mn.sub.2O.sub.3 porous microsheets electrode shows a wide response range (20 ~ 1.90 mM) and a high glucose detection sensitivity up to 6000 [mu]A mM.sup.-1 cm.sup.-2. Moreover, the value of detection limit is 12 [mu]M (S/N = 3). The anti-interference and stability tests prove that the Mn.sub.2O.sub.3 porous microsheets electrode possesses satisfactory selectivity and excellent stability. These results indicate the Mn.sub.2O.sub.3 porous microsheets electrode is potential for developing the non-enzymatic detecting devices. Graphical abstract |
