[ 1 ] - Purification and Fractionation of Carbon Dots using pH-controlled Cloud Point Extraction Technique

In this work, we describe a simple, green and general procedure for the purification and fractionation of carbon dots (CDs). CDs coated with oxygen-containing functional groups were synthesized by thermal pyrolysis of citric acid. The product of the reaction was first Purified and then fractionated into two distinct kinds of CDs (f4 and f1) using pH-controlled cloud point extraction (CPE) techn...
