Abstract

The invention provides a preparation method of a moisture power generation device based on titanium dioxide / silicon dioxide. The preparation method comprises the following steps: respectively dispersing silicon dioxide nanoparticles / nanofibers and titanium dioxide nanoparticles / nanofibers in a solvent to obtain slurry; and then respectively coating the upper end and the lower end of a substrate with the silicon dioxide nanoparticle / nanofiber slurry and the titanium dioxide nanoparticle / nanofiber slurry, coating the next region after one region is completely dried, and drying to obtain the titanium dioxide / silicon dioxide-based moisture power generation device. After the device prepared by the method and having an asymmetric structure adsorbs water in an environment, charge distribution isdifferent, so that electric energy is generated in an external circuit, and the electricity generation mode is green and environment-friendly and can be used for a humidity sensor or moisture power generation.

Description

Technical field [0001] The invention relates to the field of preparation of moisture power generation devices, in particular to a method for preparing a moisture power generation device based on titanium dioxide / silicon dioxide. Background technique [0002] Water is closely related to energy. It maintains the energy cycle of the earth system and the temperature balance of living organisms. It is a natural energy absorber, energy storage, energy converter and energy transmitter. Nearly 70% of the energy of solar radiation reaching the surface is absorbed by water. The average annual power of water dynamically absorbing and releasing energy on the earth is as high as 60 trillion kilowatts, which is 3 orders of magnitude higher than the average annual energy consumption of human beings. The traditional water energy utilization model is greatly restricted by natural conditions and is easily affected by external factors such as terrain and climate. The construction and use of large f...
