Abstract

Carbon dots (CDs) not only inherit the advantages of good biocompatibility and abundant raw material sources, but also exhibit excellent optical properties. CDs possess important research significance and application prospects in materials science, biomedicine, and catalytic degradation. In this paper, CDs were prepared from dandelions mixed with boric acid, urea, and norfloxacin respectively. We investigated the effect on the degradation efficiency of methylene blue (MB) using boron, nitrogen, and fluorine for co-doping CDs under solar light. Results show that nitrogen-doped CDs can improve photocatalytic degradation rate up to 55% which is higher than no doped CDs. That also is the best among boron-doped, fluorine-doped, and co-doping CDs with the two or three elements co-doping.
