Problems solved by technology

This is an important advance for light-driven microtubule motors, however, such motors are 2 o 2 For fuel liquid, at 0.2W / cm 2 Under the light intensity, the motor speed is about 50 μm / s. Under such a high chemical dye concentration and high light intensity, its motion performance is still insufficient, which greatly restricts the application range of the motor.
In the past, if the light-driven motor wanted to increase its motion speed, the general method was to combine it with a precious metal, such as TiO 2 -Pt,TiO 2 -Au, CuO-Au, Si-Au, BiOI-Au, etc., higher cost

Abstract

The invention relates to a ZnO-Ni photic driving micropipe motor and a preparation method thereof. The micropipe motor comprises a photocatalytic material tubular ZnO and a metal layer Ni. The micropipe motor uses hydrogen peroxide as a fuel and ultraviolet light as an excitation light source. A regulation mode of motion speed of the micropipe motor comprises fuel concentration, regulation light intensity or the content of metal Ni. The micropipe motor can effectively absorb excited electrons by utilizing the metallic properties of the Ni to reduce the charge recombination rate of ZnO, so thatthe photocatalytic performance of the ultraviolet light is effectively improved, and then the motor achieves a high-speed bubble movement in hydrogen peroxide solution; on the other hand, the magnetic properties of Ni can be used to achieve the effective motion direction control of the motor. In addition, the preparation process is simple, and the ZnO-Ni tubular photic driving micropipe motor with low cost, long service life, fast movement and controllable direction is prepared.

Description

technical field [0001] The invention relates to the micro-nano field, and relates to a light-driven micropipe motor and a preparation method thereof, in particular to a ZnO-Ni light-driven micropipe motor and a preparation method thereof. Background technique [0002] A micro-nano motor refers to a movable micro-device that converts various energies of the surrounding environment (such as chemical energy, light, sound, magnetism, electricity, etc.) into the mechanical energy of the motor itself. The size of micro-nano motors is usually nanoscale or micron scale. After functional modification, various complex and precise tasks can be performed in the micron or nanometer space. After more than ten years of development, micro-nano motors have shown excellent application prospects in the fields of cargo delivery, biomedicine, and micro-nano assembly. With the development of nanotechnology, the shape of micro-nano motors is also diversified. At present, there are several shapes ...
