The invention discloses a method for preparing a metal-organic framework thin film by utilizing a spraying method. The method comprises the following steps: taking a metal cation solution and an organic ligand solution as a spraying solution and a bearing solution; injecting the spraying solution to be atomized into a spraying device through an automatic sample feeding pump; dispersing the spraying solution to be atomized into small liquid particles in a spraying nozzle through ultrasonic waves and spraying out the solution in a fog form from the spraying nozzle; enabling the atomized solution to uniformly fall into the bearing solution under the action of gravity; enabling the two substances to be in contact on an interface to react, so as to construct a copper-terephthalic acid metal-organic framework thin film. The method provided by the invention has the advantages of simplicity in operation and convenience for controlling and industrial production; under normal temperature and normal pressure, experiment
