Carbon quantum dots (CQDs) are promising nanomaterials since they have smaller particle size, excellent biocompatibility, and low toxicity. However, no one has found their high-scale inhibition performance so far. In this article, a new kind of green scale inhibitor, carboxyl carbon (CCQDs), was synthesized through simple method thermal decomposition citric acid. The as-prepared CCQDs for CaSO4 BaSO4. With static test at temperature 0-80 °C, the antiscaling efficiency can reach 100% with additions CCQDs.
