I am synthesizing carbon dots with ethanol as the solvent. I tried to do oven drying but they stick on the wall of the glass vial. I tried to do air drying also but still the same. I tried to do freeze drying but with ethanol as a solvent, this is difficult. What are the other options?
Ethanol removal from carbon dots solution to obtain pure carbon dots can be tricky due to the tendency of carbon dots to stick to container surfaces when dried. Below are some alternative methods you might try:
It is important to note that each method might lead to slightly different results, so it may be necessary to experiment with various methods to determine which one is the most suitable for your specific application.
Joshua Depiver I wanted to try the precipitation. Is this efficient with ethanol using acetone as the solvent?
S. It can happen if your precursor is hygroscopic. According to me, freeze drying is the only option or else try vacuum drying.
