Embodiment 1
[0028] The preparation of embodiment 1 Prussian blue nano hollow rugby
[0029] (1) Preparation of cross-linked polyacrylamide microspheres
[0030] Using acrylamide (AM) as a monomer, N,N'-methylenebisacrylamide (MBA) as a crosslinking agent, ammonium persulfate (APS) as an initiator, and ethanol as a solvent, polypropylene is prepared by dispersion polymerization technology Amide microspheres. A typical synthesis process is as follows: Add 0.375 g of acrylamide (AM), 0.125 g of cross-linking agent MBA and 9.5 mL of absolute ethanol into a 50 mL round-bottomed flask, shake to dissolve, blow nitrogen gas under magnetic stirring for 20 min to remove the dissolved solution. Then add 1.91 mg APS, continue to blow nitrogen for 10 min, and then add 0.1 mL TMEDA (tetramethylethylenediamine) to the solution. Place in a 40 °C oil bath and stir overnight at a stirring speed of 600 rpm. The concentration of acrylamide monomer is 0.53 mol / L, and the ratio of acrylamide monomer to N,...
Embodiment 2
[0038] The preparation of embodiment 2 Prussian blue nano hollow rugby
[0039] (1) Preparation of cross-linked polyacrylamide microspheres
[0040] Add 0.12 g of acrylamide (AM), 0.04 g of cross-linking agent MBA and 9.5 mL of absolute ethanol into a 50 mL round bottom flask, shake to dissolve, blow nitrogen gas under magnetic stirring for 20 min to remove dissolved oxygen in the solution, and then add 1.91 mg APS, continue to blow nitrogen for 10 min, and then add 0.1 mL TMEDA (tetramethylethylenediamine) to the solution. Place in a 40 °C oil bath and stir overnight at a stirring speed of 600 rpm. The concentration of acrylamide monomer is 0.17 mol / L, and the ratio of acrylamide monomer to N,N′-methylenebisacrylamide crosslinking agent is 3:1.

Place in an oil bath at 40°C and stir overnight at a stirring speed of 600 rpm. The concentration of acrylamide monomer is 0.53 mol / L, and the ratio of acrylamide monomer to N,N′-methylenebisacrylamide crosslinking agent is 1:1.
[0046] (2) Synthesis of Prussian Blue Hollow Rugby
[0047] Add a magnetic stirring bar, 1 mL polyacrylamide / ethanol solution (polyacrylamide concentration: 50 g / mL) and 5 mL deionized water into a 10 mL glass vial, and ad...
