Method for modifying MOFs material through low-temperature plasma and application of MOFs material

The invention discloses a method for modifying a MOFs (Metal-Organic Frameworks) material by low-temperature plasma and application of the MOFs material. The method comprises the following steps that: under the condition of air tightness, argon passes through a liquid modifier, so that the argon carries saturated steam of the liquid modifier to carry out low-temperature plasma discharge reaction with MOFs, the liquid modifier is an organic reagent which is in a liquid state at room temperature or an organic reagent which is in a liquid state under an oil bath heating condition at the temperature of not higher than 100 DEG C, the low-temperature plasma discharge reaction is carried out under the conditions of room temperature and normal pressure, the discharge power is 0.5-1.5 W, and after the plasma reaction is finished, functionalized modified MOFs are obtained. The method disclosed by the invention is simple in equipment, mild in condition, low-carbon and environment-friendly, and the obtained functionalize
