Description

Technical Field

[0001] The present invention relates to the technical field of photocatalytic water splitting for hydrogen production, and particularly to an atomized photocatalytic water splitting hydrogen production device. Background Art

[0002] Some industrial hydrogen production refers to a technology that uses non-hydrogen energy sources to produce hydrogen for industrial use through physical, chemical, or biological reactions. According to the different methods of hydrogen production and the quality of hydrogen, the methods of industrial hydrogen production can be divided into three categories, namely high-temperature pyrolysis method, sodium hydride method, and electrolysis method. Among them, the electrolysis method is the water splitting hydrogen production technology. And with the rapid development of renewable energy and the continuous growth of energy demand, hydrogen energy, as a secondary energy source, is the most ideal pollution-free green energy in the new century, so it has received great attention.

[0003] Photocatalytic water splitting for hydrogen production is a method of splitting water into hydrogen and oxygen using solar energy. It uses a photocatalyst to absorb the energy of sunlight, convert light energy into chemical energy, and promote the redox reaction of water molecules to produce hydrogen and oxygen. Since sunlight is difficult to obtain, it is generally replaced by a xenon lamp light source. When existing hydrogen production devices are in use, such as an existing patent (publication number: CN217189503U) a water photolysis hydrogen production device and an existing patent (publication number: CN113913845B) a PEM photon electrolytic water hydrogen production machine, these devices generally have problems: the reactions are basically carried out in an aqueous solution. When the concentration of the catalyst is relatively high, the catalyst particles block each other, resulting in low hydrogen production efficiency of some catalyst particles. Therefore, there is an urgent need to propose an atomized photocatalytic water splitting hydrogen production device. Summary of the Invention
