Preparation method of copper azide compound, copper azide compound and application of copper azide compound

The invention discloses a preparation method of a copper azide compound, the copper azide compound and application of the copper azide compound. The preparation method comprises the steps that a sodium hydroxide solution, an organic small molecule salt solution and a copper salt solution are obtained; the method comprises the following steps: adding a copper salt solution with a first set volume into a processing container, then adding an organic small molecule salt solution into the processing container in batches, and stirring while adding, so that the organic small molecule salt solution and the copper salt solution are fully fused to obtain a mixed solution; maintaining the pH value of the mixed solution at 3-14; filtering the reacted mixed solution to obtain a first filtered product; washing the first filtration product to obtain an organic intercalation layered copper hydroxide precursor material; putting the organic intercalation layered copper hydroxide precursor material into a sodium azide solution
