Embodiment 1

[0018] Choose fresh spinach leaves with intact, deep and thick leaves, clean them and use filter paper to absorb the water and remove the stalk veins from the leaves, then weigh 10g of the leaves, cut them into pieces and put them in an ice-cold mortar, add 100mL in three times PBS buffer with a pH of 7.8, while rapidly grinding into a slurry. Subsequently, it was filtered with 4 layers of gauze with a pore size of 400 mesh, and the filtrate was centrifuged to obtain a precipitate, and 3 mL of PBS buffer with a pH of 7.6 was added to the precipitate to suspend it to obtain a chloroplast suspension. Add 20mL of an aqueous solution containing 2g of NaCl and 2mL of Triton X-100 to the resulting chloroplast suspension. After keeping it at 50°C for 15 minutes, put it in the refrigerator until precipitation occurs. Wash the precipitate with PBS buffer pH 7.6 by centrifugation After cleaning, the precipitate was suspended in 3 mL of pH 7.6 PBS buffer to prepare a 4 mg / mL thylakoid sus...

Embodiment 2

[0021] In this example, the 4 mg / mL thylakoid suspension and the 20 μmol / L manganese dioxide dispersion were mixed uniformly at a volume ratio of 100:1, and kept in a refrigerator at 4°C in the dark for 1 hour to obtain thylakoids / Manganese dioxide composite material.

Abstract

The invention discloses a photocatalytic material capable of rapidly capturing carbon dioxide and releasing oxygen. According to the invention, a thylakoid/manganese-based light-capturing oxygen-releasing composite material is prepared by utilizing photocatalytic oxygen-releasing properties of extracted in-vitro thylakoid and manganese dioxide through a material compounding preparation method, sothat the photosynthesis efficiency of the thylakoid is further improved; and the material has advantages of easy obtaining, simple preparation method, mild preparation condition, environmental protection, no pollution, biodegradability and the like, and has potential application prospects in the field of environmental protection, especially air purification.

Description

Technical field [0001] The invention belongs to the technical field of photocatalytic bionic materials, and specifically relates to a bionic composite material with the functions of capturing carbon dioxide and releasing oxygen. Background technique [0002] Photosynthesis refers to the process in which green plants and algae absorb light energy, synthesize carbon dioxide and water into energy-rich organic matter, and release oxygen at the same time. Among them, the chlorophyll on the thylakoid membrane in the chloroplast converts light energy into chemical energy. Compared with the whole cell, a single thylakoid system has many advantages. For example, a complete thylakoid membrane can better protect the proteins in the membrane, and can make the composite protein that plays a major role maintain better stability; The body itself can also provide an efficient and complete electron transfer path, and does not require nutrients to maintain. The Bao-Lian Su research group embeds ...
