Embodiment 1

[0052] A CDs / TiO 2 The preparation method of composite material, comprises the following steps:

[0053] (1) After grinding the melon seed shells, place them in a muffle furnace, calcinate them at 300°C for 4 hours, take them out after cooling, and grind them into powder. Take 1.0g of powder in a beaker, add 50mL of water and sonicate for 1h. After the solution obtained by ultrasound is filtered through a 0.22 μm filter membrane, it is centrifuged on a high-speed centrifuge at 12000 r / min for 10 minutes, the supernatant is taken, and the supernatant is bagged with a dialysis bag (MWCO=3500) and placed in twice distilled water for dialysis In two days, the water was changed every 6 hours on average to obtain CDs solution; the ultraviolet absorption spectrum and fluorescence spectrum of CDs were as follows: figure 1 Shown; TEM pictures of CDs as figure 2 shown.

Embodiment 2

[0060] A CDs / TiO 2 The preparation method of composite material, comprises the following steps:

[0061] (1) After grinding the melon seed shells, place them in a muffle furnace, calcinate them at 250°C for 3 hours, take them out after cooling, and grind them into powder. Take 2.0g of powder in a beaker, add 50mL of water and sonicate for 30min. After filtering the solution obtained by ultrasound through a 0.22 μm filter membrane, centrifuge it on a high-speed centrifuge at 10,000 r / min for 10 minutes, take the supernatant, pack the supernatant with a dialysis bag (MWCO=3500) and put it into twice distilled water for dialysis In two days, the water was changed once every 6 hours on average to obtain the CDs solution; the absorption spectrum and fluorescence spectrum of CDs were as follows: Figure 9 Shown; TEM pictures of CDs as Figure 10 shown.

Abstract

The invention discloses a preparation method of a CDs / TiO2 composite material, a production method of a modified EVA film, and an application of the modified EVA film. The CDs / TiO2 composite nanomaterial is prepared from melon seed shells, EVA is modified, and the modified EVA film is used as a photocatalyst to realize degradation of acid fuchsin and rhodamine B. The EVA has no water-soluble properties, so the EVA is applied to degrade the acid fuchsin in organic wastewater in order to effectively reach degradation and provide convenience for curing, cycle use and recovery of the catalyst.

Description

technical field [0001] The invention belongs to the field of material preparation, in particular to a CDs / TiO 2 A preparation method of a composite material, a preparation method of a modified EVA film and an application thereof. Background technique [0002] Carbon dots (CDs) are environmentally friendly fluorescent nanomaterials with similar optical properties to semiconductor quantum dots. In addition to the advantages of traditional semiconductor quantum dots such as excellent optical properties and small size, they also have low cytotoxicity and biological It has incomparable advantages such as good compatibility, easy large-scale synthesis and functional modification, low preparation cost and mild reaction conditions. Therefore, it has good application prospects in the fields of cell imaging, labeling and detection, and is a good choice to replace quantum dots. At present, CDs have been initially applied in the fields of cell imaging, light-emitting devices, catalysi...
