Nano-engine, method for providing power for nano-engine, and application of nano-engine

Abstract

The invention belongs to the field of nanotechnology, and particularly relates to a nano-engine, a method for providing power for the nano-engine, and application of the nano-engine. The nano engine comprises: a shell with an opening, wherein a nickel-plated graphite layer is arranged in a first area of the inner wall of the shell, and an iridium oxide layer is arranged in a second area of the inner wall of the shell; and a power supply assembly. According to the nano-engine, the nickel-plated graphite layer serves as the cathode base body, and the iridium oxide layer serves as the anode basebody, so that the nano-engine has a high electrolysis rate on water molecules, and sufficient and stable power can be provided by electrolyzing the water molecules. The method for providing power forthe nano-engine comprises the following steps that the nano-engine is placed in an electrolytic solution, and electrolyzes water molecules in the electrolytic solution in the inner cavity of the shellof the nano-engine to generate bubbles so as to provide driving force. Hydrogen and oxygen generated by electrolyzing water molecules are used as power of the nano-engine, the speed of generating bubbles by electrolyzing the water molecules is easy to control, and enough kinetic energy can be provided for the nano-engine.

Problems solved by technology

[0004] At present, a kind of nanomotor is prepared by cathode electrochemical reaction 2H 2 o 2 =2H 2 O+O 2 ↑, decomposes into water in the permanganate ion solution, releases oxygen at the same time, and generates forward propulsion through gas release in the pipe-type micro-nano engine, but due to the use of MnO 2 As a catalyst, its activity and catalytic efficiency are limited, so the decomposition rate of hydrogen peroxide is very slow, and the kinetic energy provided is relatively small, which cannot guarantee the energy required by the nanorobot during the movement process.

Therefore, the working efficiency of this type of nanoengine is relatively low, and the rate of chemical reaction can only be guaranteed by increasing the concentration of hydrogen peroxide solution.

On the other hand, hydrogen peroxide solution is recognized as a low-toxic substance because of its strong oxidizing properties. When it enters human blood and other substances, it will cause problems such as vascular embolism.
