Abstract
The present invention provides a hybrid nanomaterial electrode, comprising a pair of spaced-apart electrodes, at least three pairs of metallic nanowires disposed between the electrodes and respectively connected with the electrodes, and at least a detecting material connecting with the metallic nanowires. The detecting material is formed as a semiconductor nanostructure or a conductor nanostructure. The hybrid nanomaterial electrode of the present invention can be used in a gas detector for detecting volatile organic compounds, and has the advantage of providing high sensitivity, low detection limit, and the ability to operate at room temperature.
