At present, catalysts for water synthesis and decomposition reactions on the basis of hydrogen and oxygen are mainly metal oxides of the same valence state, single metals, or several composite single metals. Related patents of an X3O4 compound consisting of a compound with two valence states are not available. Although nanostructuring can partially improve the catalytic activity, the problem of stability is caused, and the catalytic activity is still low. Moreover, the high cost and severe scarcity of noble metals dramatically limit the application. The major problem is that the reaction conditions require a high energy condition, and a reaction environment that is prone to destroy a medium in a catalyst reactor, making the cycle life prone to be shortened. Seeking a low-cost, efficient, and stable catalyst is an important solution to current energy supply. In the new invention, through a novel synthesis technology, crystal defects of an X3O4 product in the current technical field are greatly reduced and repaired, so that an original amorphous structure and crystal structure of the product show another functional activity that under the condition of very low energy provided from the outside, electron gain and electron loss reactions between hydrogen and oxygen in water can be accelerated, resulting in a new important function of the X3O4under a low reaction condition, electron gain and loss between hydrogen and oxygen in water are strongly catalyzed, and a compound that strongly catalyzes the synthesis of carbon-oxygen bonds (comprising covalent states) and catalyzes the synthesis of carbon-hydrogen bonds is achieved. Existing X3O4 compounds have no catalytic activity at room temperature, and the water decomposition activity is not increased even high electric energy, chemical energy, and light energy. The element X in X3O4 comprise elements known before the patent is valid that can simultaneously form stable divalent and trivalent cation, such as iron, cobalt, nickel, and manganese. For example, for FeFe2O4, assuming that a crystal has 90 single molecules, there are 90 divalent Fe and 180 trivalent Fe in a 1:2 ratio. At present, the products are seriously disordered, not in a ratio of 90 / 180, and possibly 81 / 189, and there is much more trivalent Fe in some cases. The local electron motion of the molecule is disordered and changed, thereby seriously affecting the performance of the product. The patent product is strictly controlled, and thus the performance is greatly improved. Modern technologies comprising crystal structure detection and amorphous substance detection means cannot distinguish existing products from our product except for the catalytic performance under the current technical capabilities.
