[0046] The invention provides a kind of preparation method of polymolybdophosphoric acid-nitrogen heterocyclic salt supramolecular compound, and described preparation method comprises the following steps:
[0047] step one:
[0048] Weigh the polymolybdenum phosphate and nitrogen heterocyclic rings, place them in the reaction solution, stir to make them fully dispersed, add an acid regulator dropwise to adjust the pH of the reaction solution to 1.0-5.0, and continue stirring to completely dissolve the reaction materials.
[0049] The polymolybdenum phosphate refers to a metal phosphate containing multiple molybdenum atoms, such as hexamolybdenum tetraphosphate, dodecamolybdenum phosphate, octadecyl molybdenum diphosphate, octadecademolybdenum hexaphosphate or pentamolybdenum diphosphate Salt;
[0050] Preferred are octadecyl molybdenum diphosphate and octadecadeca molybdenum hexaphosphate;
[0051] It is more preferred to use octadecyl molybdenum diphosphate, the anion in th...
Embodiment 1
[0160] (1) Preparation of octadecadectamolybdenum diphosphate di(4,4') bipyridine hexaammonium salt;
[0161] 0.4g (NH 4 ) 6 P 2 Mo 18 o 62 2H 2 O, 0.043g C 10 h 8 N 2 (4,4'-Bipyridine) was added to a mixed solution of 5mL distilled water and 3mL absolute ethanol, stirred until uniformly dispersed, adjusted the pH of the solution to 2.0 with dilute nitric acid, and stirred for 1 hour to completely dissolve; then the reaction solution was placed in Seal it in a stainless steel reaction kettle with a filling degree of 50%; place the sealed stainless steel reaction kettle in an oven with a temperature of 150°C, heat it for 4 days, and obtain block crystals after cooling at room temperature, wash with distilled water and dry at room temperature to obtain the compound 1, 0.195 g, yield 44.1%.
[0162] (2) Preparation of compound 1 and graphene oxide mixture modified electrode;
[0163] Select the bare glassy carbon electrode as the base electrode, first polish the bare gl...
Embodiment 2
[0172] (1) Preparation of octadecadectamolybdenum diphosphate tetrapyridinium hexammonium salt;
[0173] 0.4g (NH 4 ) 6 P 2 Mo 18 o 62 2H 2 O. Add 0.043g of pyridine to the mixed solution of 5mL of distilled water and 3mL of absolute ethanol, stir until uniformly dispersed, adjust the pH of the solution to 1.5 with dilute nitric acid, and stir for 1.5 hours to completely dissolve it; then place the reaction solution in a stainless steel reactor Internally sealed, the filling degree is 45%; the sealed stainless steel reaction kettle is placed in an oven with a temperature of 160°C, heated for 4 days, cooled at room temperature to obtain blocky crystals, washed with distilled water and dried at room temperature to obtain compound 1, which is 0.187 g, the yield was 42.3%.
[0174] (2) Preparation of compound 1 and graphene oxide mixture modified electrode;
[0175] The method is the same as that in Example 1(2).
[0176] (3) Preparation of compound 1-polypyrrole-graphene ...
