Abstract: Provided is a three-phase system V2O3/VN/Mo2C nanoelectrode material, and a preparation method and application thereof. The nanoelectrode material comprises V2O3 particles, VN particles, and Mo2C particles. The V2O3 particles, VN particles, and Mo2C particles are interlaced in lattice stripes and are uniformly distributed. The mass ratio of the V2O3, VN and Mo2C is (1 to 4):(10 to 40):(4 to 16). The above-mentioned three kinds of nanoparticles are intertwined to form more incoherent interface area. The increase in the area of the incoherent interface area will cause more defects, so that more active sites are provided, and the hydrogen production performance is improved.

The system includes a command generator, a filter, a tactile driver and a linear resonant actuator; the command generator generates an initial commanding signal according to an input signal; the filter filters the initial commanding signal so that amplitudes of a predetermined number of initial pulses of the filtered commanding signal are larger than a set threshold and phases of a predetermined number of ending pulses reverse; and the tactile driver generates a driving signal according to the filtered commanding signal for driving the actuator to vibrate. The initial commanding signal generated by the command generator is filtered so that when the actuator is driven to vibrate by the driving signal generated subsequently, the actuator has a quick starting response and a quick braking response.
