Carbon nanostructures are highly promising materials for applications in a variety of different fields. Besides their interesting performances, the possibility to synthesize them from biowaste makes an eco-friendly resource widely exploitable within circular economy context. The present work deals with green, one-pot synthesis graphene quantum dots (GQDs) carbon aerogels (CAs) derived rice husk (RH). After having obtained CAs upon purification RH, followed by gelification and carbonization resulting cellulose, solventless production GQDs was ball milling. This method determined formation crystalline diameter around 20 nm, which were analyzed via scanning electron microscopy, transmission atomic force X-ray diffraction, Raman spectroscopy obtain full morphological structural characterization. used as electrode supercapacitors Li-ion batteries, showing ability both accumulate charges over surface intercalate lithium-ions. reported results proof principle exploiting support material development advanced systems energy storage.
