I want to make some nanoparticles from carbon-based such as PAC, but the size is only one micrometer tops, my colleague suggested using the hydrothermal technique but is that possible? since I have no references for it?
Yes, it is possible to synthesize carbon-based nanoparticles with a size of one micrometer or less using the hydrothermal technique. In this method, carbon precursors are dissolved in a liquid and subjected to high pressure and temperature in a sealed vessel. Under these conditions, the carbon precursors undergo nucleation and growth, forming nanoparticles.
There are many research articles available on the synthesis of carbon-based nanoparticles using the hydrothermal technique. You can search for these articles using keywords such as "carbon-based nanoparticles," "hydrothermal synthesis," and "particle size control." Additionally, you can consult with experts in the field or with experienced colleagues who have worked with similar materials and techniques.
It is important to note that the hydrothermal technique requires specialized equipment and expertise, and safety precautions must be taken when working with high pressure and temperature. Therefore, it is recommended to conduct this process under the guidance of a qualified researcher with experience in this field.
