Nanoflowers are a recent class of nanomaterials that show structural similarity to plant flowers. Among these structures, carbon nanoflowers (CNFs) stand out as promising materials for application in electrochemistry, gas adsorption and absorption, batteries and supercapacitors. This paper innovates by presenting a method for CNFs production using electric arc (EA) discharge in water. The main advantage of using water instead of other liquid media is the possibility of reusing that water several times, reducing its waste in an eco-friendly process. X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) show that the yielded CNFs present high quality (ID/IG = 1.03), homogeneity and purity. The low-cost and simplicity of CNFs synthesis by EA in water make their production on an industrial scale attractive.

Abstract
Nanoflowers are a recent class of nanomaterials that show structural similarity to plant flowers. Among these structures, carbon nanoflowers (CNFs) stand out as promising materials for application in electrochemistry, gas adsorption and absorption, batteries and supercapacitors. This paper innovates by presenting a method for CNFs production using electric arc (EA) discharge in water. The main advantage of using water instead of other liquid media is the possibility of reusing that water several times, reducing its waste in an eco-friendly process. X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) show that the yielded CNFs present high quality (ID/IG = 1.03), homogeneity and purity. The low-cost and simplicity of CNFs synthesis by EA in water make their production on an industrial scale attractive.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
