The invention relates to a method for preparing carbon-film-coated tungsten oxide nanospheres in one step by using a hydrothermal process and application of the carbon-film-coated tungsten oxide nanospheres. The method comprises the following steps: respectively acquiring tungstate and a carbon source according to a mass ratio of 1: 0.5 to 1: 5, adding the tungstate and the carbon source into deionized water, and carrying out sufficient dissolving to obtain a mixed solution; putting the mixed solution into a reaction kettle, and performing natural cooling after a hydrothermal reaction to obtain a reacted turbid liquid; and cleaning and centrifuging the reacted turbid liquid with deionized water and ethanol, and performing vacuum drying to obtain the carbon-film-coated tungsten oxide nanospheres. The invention also provides a glucose detection sensor electrode prepared from the carbon-film-coated tungsten oxide nanospheres. Compared with the prior art, the preparation method disclosed by the invention has the
