Embodiment Construction
[0029] Any feature disclosed in this specification, unless specifically stated, can be replaced by other alternative features that are equivalent or have similar purposes. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.
[0030] A rapid preparation method of carbon nanoparticles loaded with visible light Au, the preparation method is as follows: take 1g of graphite, put it into a container containing 5M, 150ml H 5 PMo 10 V 2 o 40 In a three-neck flask, set up a reflux device. Stir at room temperature for 30 minutes, then reflux for 2 hours at 140°C in a boiling state. After the three-necked flask was cooled to normal temperature, the reflux liquid was introduced into a 500-type dialysis bag, and the dialysis bag was soaked in deionized water for 1 day, during which time the water was changed every 6 hours. After infiltration, the solution in the dialysis bag was adjusted to pH 6.5 with 0.25M ammon...

Abstract
The invention discloses a rapid preparation method of carbon nanoparticles loaded with Au by visible light, which comprises the following steps: taking graphite and putting it into a 5 PMo 10 V 2 o 40 In a three-necked flask, set up a reflux device, stir, and then reflux at 140°C for 24 hours in a boiling state; cool the three-necked flask to room temperature, introduce the reflux liquid into a dialysis bag, and then infiltrate the dialysis bag in deionized water; Finally, adjust the pH value of the solution in the dialysis bag to 6.5; put the above solution into a centrifuge tube for centrifugation, then take 5ml of the supernatant, and dilute it to 50ml with deionized water; introduce the diluted solution into the photoreactor for irradiation, At the same time, the prepared 0.5ml, 0.1M HAuCl 4 ·3H 2 The O solution is quickly added to the reactor several times; after the reaction, a suspension is obtained, and the suspension is dried to obtain Au-loaded carbon nanoparticles on solid particles. The invention is more economical, convenient and environmentally friendly.
Description
technical field [0001] The invention relates to a preparation method of nano carbon, in particular to a preparation method of Au-loaded carbon nano particles. Background technique [0002] Different carbon nanomaterials have different functions. For example, graphitic carbon nanoparticles have strong adsorption capacity and are easy to adsorb with tissue cells. This type of nanoparticle has good cytocompatibility and sensitization effect, and has great potential value in the field of cytology. As an emerging material, carbon nanomaterials also play an important role in military and national defense; surface functionalized carbon nanoparticles with gold or platinum coatings can be used as photoreductants to catalyze CO 2 Converted into hydrocarbons; Fluorescent carbon nanoparticles not only have good biocompatibility and easy surface functionalization, but also have the characteristics of switching fluorescence emission and stable emission, so they have important application...
