Cuprous oxide nanometer thin-film electrodes of different structures were successfully prepared by electrochemical deposition. The structures and properties of the samples were characterized by X-ray diffractometer, ultraviolet-visible and scanning electron microscope. The cuprous oxide thin-film electrode was used as a non-enzymatic glucose sensor, and the electrocatalytic response of the sensor for glucose was investigated by cyclic voltammetry. Results showed that cuprous oxide with higher purity, neat morphology structure and uniform grain size was prepared. The cuprous oxide nanometer thin-film sensor with a sword-shaped dendrite has a good response to glucose. Moreover, it has a good linear relationship of 1-20 mg.L-1 in the range of glucose concentration, a correlation coefficient of 0.997, a detection limit of 0.337 mg.L-1, a sensitivity of 23.24 mA.cm(-2).mM(-1) and good stability. Therefore, it has potential for application in sensors.
