PROBLEM TO BE SOLVED: To produce hydrogen, which is attracting attention as a clean energy source, by thermochemical decomposition of water, it is possible to efficiently use a lower temperature heat source, yet there is no generation of by-products that cause environmental problems, and it is corrosive. Development of possible ways to avoid the use of substances. Hydrogen and oxygen production by continuous thermal decomposition of water is a reaction with water catalyzed by aluminate ions in the presence of an aluminate ion donor and the accompanying hydrogen and oxygen (including hydrogen peroxide). This is done by including a hydrogen and oxygen production cycle by the decomposition of water consisting of the production of The reaction system can be efficiently carried out at about 190 to 200 ° C., and hydrogen and oxygen can be produced from water at low cost even when using a relatively low-temperature heat source such as waste heat.
