摘要

利用生物质热解副产物焦油为碳前驱体，采用反相微乳液法和P

碳化法制备了荧光碳量子点。反相微乳液法制备的碳量子点为规则球状结构，粒径均一，平均粒度为4.3 nm，晶面间距为0.25 nm，对应于石墨碳的（100）晶面；P

碳化法制备的碳量子点为蜂窝状结构，平均粒径为6.8 nm，晶面间距为0.33 nm，对应于石墨碳的（002）晶面。两种方法制备的碳量子点均具备石墨结构特征，碳量子点荧光产率分别为85.3%和24.3%。

Abstract

By using the reverse microemulsion method and P

carbonization method

the fluorescent carbon quantum dots were prepared using pyrolysis by-products tar as carbon precursor. The carbon dots prepared by reverse microemulsion method are regular spherical structures with uniform particle size of 4.3 nm and the crystal lattice spacing is 0.25 nm

corresponding to the (100) plane of graphite carbon. The carbon quantum dots prepared by P

carbonization method are honeycomb-like with particle size of 6.8 nm and the crystal lattice spacing is 0.33 nm

corresponding to the (002) plane of graphite carbon. The yield of carbon quantum dots is 85.3% and 24.3%

respectively.
