[0038] The preparation methods of the zinc hydroxide nanowire solution in the following examples are: adding ethanolamine to the mixed solution of ethanol and water to obtain the ethanolamine solution; adding zinc nitrate to the mixed solution of ethanol and water to obtain the zinc nitrate solution; Equal volumes of the ethanolamine solution and the zinc nitrate solution were mixed, and after magnetic stirring, the reaction vessel was sealed, and after standing for 0.5 hours, a zinc hydroxide nanowire solution was obtained. The concentration of the ethanolamine solution is 1.6mM; the concentration of the zinc nitrate solution is 4mM; the volume ratio of ethanol and water in the mixed solution of ethanol and water for dissolving ethanolamine or zinc nitrate is 1:1.5; the The magnetic stirring time after mixing the ethanolamine aqueous solution and the zinc nitrate aqueous solution was 4 minutes.

[0042] (1) if figure 1 As shown, 10mL zinc hydroxide nanowire solution was mixed with 2mL 24.4μg / mL R-phycoerythrin aqueous solution, and after magnetic stirring for 5min, it was directly vacuum filtered on the polycarbonate membrane to form a layer of zinc hydroxide nanowire and A composite membrane of R-phycoerythrin, and then transfer the composite membrane to a silicon wafer, wherein the polycarbonate membrane has a diameter of 2cm and a pore size of 200nm;
[0043] (2) Put the composite film of R-phycoerythrin and zinc hydroxide nanowires into 5 mL of 25 mM 2-methylimidazole solution, and react at room temperature for 24 hours. After the reaction, wash 3 times with a mixed solvent of ethanol and water with a volume ratio of 1:4 to obtain an R-phycoerythrin / metal organic framework composite film, wherein the mass ratio of ZIF-8 and R-phycoerythrin is 20: 1. Such as figure 2 and image 3 The R-phycoerythrin / MOF composite film shown is a polycrystalline film with good g...

[0045] (1) Mix 10mL zinc hydroxide nanowire solution with 3.6mL 24.4μg / mL R-phycoerythrin aqueous solution, stir magnetically for 5min, and vacuum filter directly on the polycarbonate membrane to form a layer of zinc hydroxide nanowire A composite membrane with R-phycoerythrin, and then transfer the membrane to a silicon wafer, wherein the polycarbonate membrane has a diameter of 2 cm and a pore size of 200 nm;
[0046] (2) Put the composite film of R-phycoerythrin and zinc hydroxide nanowires into 5 mL of 25 mM 2-methylimidazole solution, and react at room temperature for 24 hours. After the reaction, wash 3 times with a mixed solvent of ethanol and water with a volume ratio of 1:4 to obtain an R-phycoerythrin / metal organic framework composite film, wherein the mass ratio of ZIF-8 and R-phycoerythrin is 10: 1. Such as Figure 4 The R-phycoerythrin / MOF composite film shown is a polycrystalline film with good grain intergrowth and continuous film without cracks.
