specific Embodiment approach 2
[0027] Specific embodiment two: the present embodiment is a kind of preparation method that phosphomolybdic acid constructs multi-acid base cadmium metal hybrid material and is completed according to the following steps:
[0028] One, prepare the reaction solution with a pH value of 1.5: dissolve phosphomolybdic acid, cadmium nitrate, and 2,2-bipyridyl organic ligands into deionized water to obtain a reaction solution; adjust the pH value of the reaction solution to 1.5 to obtain a pH value 1.5 reaction solution;
[0029] The mol ratio of phosphomolybdic acid and metal cadmium salt described in step 1 is: 0.1: (0.2~1);
[0030] The molar ratio of phosphomolybdic acid and 2,2-bipyridine organic ligand described in step 1 is: 0.1:(0.2~0.5);
[0031] The volume ratio of the amount of substance of the phosphomolybdic acid described in step 1 to distilled water is: 0.1mmol: (20ml~40ml);
[0032] 2. Add the reaction solution with a pH value of 1.5 into a polytetrafluoroethylene re...
