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.
