摘要：
Cu2O/AlOOH/rGO nanocomposites were synthesized by employing AlOOH/rGO as the support for Cu2O catalysts and then the nanocomposites were used for fabricating nonenzymatic glucose sensors. The morphology and composition of the nanocomposites were characterized by transmission electron microscopy and X-ray diffraction spectroscopy. Electrochemical investigations indicate that the nanocomposites possess an excellent performance toward glucose with a wide linear range of 5.0 mu M to 14.77 mM, a sensitivity of 155.1 mu A mM(-1) cm(-2) and a low detection limit of 2.6 mu M. These results indicated that the Cu2O/AlOOH/rGO modified electrode can act as a promising non-enzymatic sensor for glucose detection.
