A photothermomagnetic coupling hydrogen production experimental device based on magnetic particles

Abstract

The invention discloses a photo-thermal magnetic coupling hydrogen generation experiment device based on magnetic particles. The device mainly comprises a magnetic field generator, electric heating panels, a light source, mirror surface reflecting panels and the like to provide a coupling multi-physical-field experiment device for current burgeoning magnetic photocatalytic particles and provide experiment conditions for further scientific study of science researchers. According to the photo-thermal magnetic coupling hydrogen generation experiment device, an intermittent pulsed magnetic field with opposite polarities can be generated through the magnetic field generator, and the position of the magnetic field generator, the size of the magnetic field and the pulse time can be artificially set according to experiment needs. An existing instrument can be selected as the light source to utilize existing resources to the maximum. By arranging the mirror surface reflecting panels, the light utilization rate can be increased, and it can also be avoided that the temperature of the light receiving face of the back face of a controller is too high. An electric heating mode is adopted for the electric heating panels, constant-temperature heating can be carried out through control of the temperature controller, and safety and convenience are achieved. The device is used for photocatalytic hydrogen generation experiments of magnetic catalyst particles, and has the advantages of being simple in structure, convenient and fast to operate and stable in operation.

Description

[0001] Technical field: [0002] The invention belongs to the field of new energy preparation, and in particular relates to a photothermomagnetic coupling hydrogen production experimental device based on magnetic particles. [0003] Background technique: [0004] In recent years, the world is facing severe challenges of energy crisis and environmental pollution, and it is imminent to seek clean, green and sustainable new energy sources. The emerging semiconductor photocatalysis technology provides us with a method to directly generate hydrogen gas by using catalyst powder to shine in water through sunlight. Since solar energy is inexhaustible, and hydrogen energy is an ideal energy source that is green, high in combustion value, pollution-free, and recyclable, hydrogen production through photolysis of water is an effective way to solve energy problems. [0005] The reaction mechanism of photocatalytic water splitting to produce hydrogen is based on the semiconductor energy ban...

AI Technical Summary

Problems solved by technology

In view of the fact that in the existing experimental device, the added magnetic catalyst particles will be adsorbed on the surface of the magnet, and some of them will be deposited on the bottom of the vessel, which cannot achieve a uniform suspension state, which will have a great impact on the experiment

In this way, the existing experimental device cannot apply magnetic field, optical field and thermal field to the reaction system at the same time, so it cannot provide ideal coupling field experimental conditions, so it is necessary to design a new experimental device to solve the above problems
