Preparation of Fluorescent Carbon Quantum Dots from Sweet Potato Peel
Biomass fluorescent carbon quantum dots had advantages such as high safety,high stability,and convenient synthesis,and had broad applications.This article used high-temperature reaction vessels,centrifuges,and other reaction devices to prepare fluorescent carbon quantum dot solutions from raw sweet potato peel.Through single factor and orthogonal experiments,the optimal synthesis conditions were as follows:0.1 g sweet potato peel powder and 20 mL deionized water were added to the reaction vessel and mixed evenly,and the reaction was carried out for 80 min at a temperature of 160 ℃.The fluorescence intensity of the obtained fluorescent carbon quantum dot solution was the best.We hope that our research can provide reference for the preparation of fluorescent materials using natural products as raw materials.
