A facile method to control the morphologies of barium sulfate particles by using carboxylic carbon quantum dots as a regulator

A very simple method to control the morphologies of BaSO4 particles was reported for the first time. Various morphologies of BaSO4 particles including rectangle, shuttle-like, flower-like and so on were prepared by using carboxylic quantum dots (CCQDs) as morphological regulators in presence of NaCl. The formation mechanism was deduced at the same time.

Automated summary

By using carboxylic quantum dots as morphological regulators, the morphologies of BaSO4 particles can be controlled, resulting in various shapes such as rectangle, shuttle-like, and flower-like. The formation mechanism was also deduced.
