Problems solved by technology

However, the inner diameter of the ordinary microchannel reactor used is very small, and the carbon source milk is rich in protein, sugar, lipid and other macromolecules, which can easily block the microtubules, reduce production efficiency, and affect product quality. The microchannel reactor can be used repeatedly short, increase production cost

Description

technical field [0001] The invention belongs to the technical field of preparation of nanometer functional materials, and in particular relates to a device and method for preparing carbon quantum dots by using orange juice solution as a precursor. Background technique [0002] Carbon quantum dots are zero-dimensional carbon-based nanomaterials composed of spherical particles with a particle size of less than 10 nm. Because carbon dots have the characteristics of wide source of raw materials, low toxicity, good fluorescence stability, good biocompatibility, and environmental friendliness, they have broad application prospects in the fields of luminescent materials, metal ion detection, medical imaging technology, and environmental monitoring. . With the vigorous development of current technology, carbon quantum dots will also have broad prospects in the development direction of scanning technology, such as two-dimensional code scanning and laser scanning, by virtue of their ...
