氮硅自掺杂竹基碳量子点及其光催化复合材料的制备与应用
Preparation and Application of N,Si Auto-doped Carbon Quantum Dots and Photocatalytic Composites
摘要
Abstract
Based on the fact that bamboo is rich in nitrogen(N)and silicon(Si),this study utilized bamboo residue as a raw material to prepare nitrogen and silicon auto-doped bamboo-based carbon quantum dots(N,Si-CQDs)via hydrothermal method,further combined with BiOCl to form N,Si-CQDs/BiOCl composites.Compared with the residues from eucalyptus and Masson pine pulping,bamboo pulping resi-dues exhibited a higher Si content(2.31%)and relatively higher N and O contents,highlighting their unique advantages for high-perfor-mance carbon materials preparation.The study revealed that N,Si-CQDs/BiOCl achieved a photocatalytic degradation rate of 92.5%for tetra-cycline hydrochloride(TCH)within 160 min,with hydroxyl radicals(·OH),superoxide radicals(·O2-),and holes(h+)identified as the primary active species.The auto-doping of N and Si significantly enhanced the electron transport capacity of carbon quantum dots,promoting the separation and migration of photogenerated charge carriers.The strong interaction between N,Si-CQDs and BiOCl through C—O—Bi chemical bonds enhanced the catalyst's oxygen vacancy concentration and facilitates efficient electron transfer,thereby boosting the photocat-alytic effect.关键词
