Embodiment 1
[0021] A Prussian blue analog / Cu x -Co y -MOF composite material, its structural composition can be expressed as: ZnCoPBA / Cu 0.75 -Co 0.25 -MOF, the composite material is based on the Prussian blue analog ZnCoPBA as the matrix and Cu 0.75 -Co 0.25 -MOF is the active component, and the active component is loaded on the surface of the Prussian blue analog.
[0022] The ZnCoPBA / Cu 0.75 -Co 0.25 -The preparation method of MOF composite material specifically comprises the following steps:
[0023] (1) Put 100mL K 3 [Co(CN) 6 ] solution was slowly added dropwise to 100 mL of ZnCl 2 A new mixed solution was obtained from the solution; the new mixed solution was stirred at a constant speed for 2 h, and placed at room temperature for 24 h;
[0024] (2) The material in step (1) was centrifuged to collect the precipitate, and the precipitate was washed three times with deionized water and ethanol; the obtained solid was dried under vacuum at 60 °C for 8 hours to obtain a white ...
