| description | The invention provides a preparation method of a bimetallic catalyst Pd@Cu-BTC removing nitrate in a water body and application of the bimetallic catalyst. The preparation method comprises the following steps that 1, activation is conducted on Cu-BTC; 2, the activated Cu-BTC in the first step is put in n-hexane to form a uniform disperse system; 3, a chloropalladic acid solution is dropwise added to the system in the second step, and stirring, filtering and drying are conducted; 4, the material obtained in the third step is put into a tube furnace for calcination, reduction is conducted with H2, vacuum drying is conducted, and the Pd@Cu-BTC catalyst is obtained. The catalyst is prepared into an electrode, and catalytic reduction is conducted on the nitrate through an electrochemical mode. The catalyst is high in activity, good in stability, high in nitrogen selectivity and high in processing efficiency, secondary pollution cannot be produced, and the preparation method of the bimetallic catalyst Pd@Cu-BTC rem |
