Abstract

The invention discloses a preparation method of an antioxidant based on Al-CQDs and Al-CNSs, and belongs to the field of antioxidant application. According to the invention, a Ti3AlC2MAX phase is used as a carbon source, and Al-doped carbon quantum dots and Al-doped carbon nanosheets (Al-CQDs and Al-CNSs) are respectively prepared in an electrolyte by using an electrochemical method and regulating and controlling electrolysis voltage. The oxidation resistance of the prepared Al-CQDs and Al-CNSs is tested, so that the oxidation resistance of the Al-CQDs and the Al-CNSs is detected. The preparation method disclosed by the invention is simple, short in preparation period, low in cost and environment-friendly, and has certain commercial feasibility; and the prepared Al-CQDs and the prepared Al-CNSs both have excellent oxidation resistance.

Description

technical field [0001] The invention relates to the field of anti-oxidation applications, in particular to the preparation of an antioxidant based on aluminum-doped quantum dots (Al-CQDs) and aluminum-doped carbon nanosheets (Al-CNSs), and belongs to the technical field of carbon materials. Background technique [0002] High-efficiency antioxidants can control the concentration of ROS and scavenge excess free radicals. Free radicals refer to molecules, atoms, ions or groups with one or more unpaired electrons in the outer orbit. Reactive oxygen species (ROS) are highly reactive free radicals derived from oxygen molecules and some molecules, including singlet oxygen ( 1 o 2 ), hydrogen peroxide (H 2 o 2 ), superoxide radicals (O 2 · - ), hydroxyl radicals (OH) and nitric oxide (NO), etc. An appropriate amount of ROS can repair or remove damaged cells and prevent cells from dying due to oxidative stress. However, the damage caused by excessive ROS accumulation to the h...
