Abstract

The invention discloses a copper oxide nano-belt and a preparation method thereof. The preparation method of the copper oxide nano-belt comprises: a step of preparing a first mixed solution of emulsifier and normal hexane, a step of preparing a second mixed solution containing copper salt, a step of carrying out a copper hydroxide precipitation reaction and a step of heat treating copper hydroxide precipitate. In the preparation method of the copper oxide nano-belt, emulsion template technology at room temperature is adopted, the copper salt solution and ammonia water are used as raw materials, precipitation is directly carried out under the action of the emulsion template formed by an oil phase of normal hexane and emulsifier and a water phase to prepare copper hydroxide, and the copper hydroxide is heated to convert into a CUO nano-belt with nano holes. The preparation method is low in necessary temperature, simple and convenient to operate, good in reproducibility, high in yield and low in cost, and the size and morphology of the copper oxide nano-belt can be controlled by regulating and controlling the reaction conditions. The nano holes are distributed on the surface of the prepared prepared copper oxide nano-belt, thereby having large specific surface area and excellent physical and chemical properties on the surface.
