specific Embodiment approach 1
[0019] Embodiment 1: This embodiment is a preparation method of metal organic framework material Ni-based MOF-74, which is realized according to the following steps:
[0020] 1. Use detergent, acetone, deionized water and absolute ethanol to ultrasonically clean the ITO glass in turn, and then perform plasma hydrophilization treatment after drying to obtain the treated ITO glass;
[0021] 2. Using DMF as solvent, prepare 1~10mmol / L Ni(NO) 3 ) 2 ·6H 2 O and 1~10mmol / L 2,5-dihydroxyterephthalic acid solution;
[0022] 3. Take the above Ni (NO 3 ) 2 ·6H 2 O, 2,5-dihydroxyterephthalic acid solution and deionized water were mixed and transferred to a 6 mL round-bottomed glass tube. It is placed in a reaction kettle and reacted at 110-130° C. for 10-14 hours to obtain a metal-organic framework material, which is Ni-based MOF-74, and the preparation method is completed.
specific Embodiment approach 2
[0023] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the ultrasonic cleaning time in step 1 is 15-25 minutes. Other steps and parameters are the same as in the first embodiment.
specific Embodiment approach 3
[0024] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the plasma hydrophilization treatment in step 1: the dried ITO glass is soaked in a 1 mol / L KOH ethanol solution for 30 minutes. Other steps and parameters are the same as in the first or second embodiment.
