Carbon nanoparticles from lignite
Kohoutková, Eliška ; Enev, Vojtěch (referee) ; Pekař, Miloslav (advisor)
These bachelor thesis focuses on lignite as a potential raw material for the carbon quantum dots extraction. There was proposed mechanochemical process of isolation these nanoparticles from lignite based on literature search. Lignite was mechanically stressed and subsequently oxidized to hydrogen peroxide. The results show that proposed method will have to be modified but lignite could be used as a feedstock for the carbon quantum dots extraction.

South-Moravian lignite as a source of carbon nanoparticles
Drozdová, Miroslava ; Taraba, Boleslav (referee) ; Pekař, Miloslav (advisor)
This Master’s thesis deals with isolating carbon nanoparticles from South Moravian lignite using "green" – environmentally friendly methods. This method consists of mechanical-chemical-thermal stressing of lignite using ultrasound, hydrogen peroxide and high temperatures. This work aims to develop recommendations on coal as a source of carbon nanoparticles and based on these recommendations, to design procedures for isolating nanoparticles from South Moravian lignite using environmentally friendly methods. The identified procedures were designed to meet carbon-based particles with an oxidized surface. From the results we can deduct that it is possible to use South Moravian lignite for the preparation of carbon nanoparticles. However, it will be necessary to modify the process further and also to optimize the purification of the obtained particles.
