Sustainable Synthesis of HighSurfaceArea Graphite Oxide ...
A sustainable route to produce graphite oxide (GO) is presented using dry ball milling. The production method was based on pristine graphite flakes in a planetary ball mill. The prepared GO was characterized using UV–vis spectroscopy, BET surface area analysis, thermal analysis, SEMEDX, TEM, XPS, elemental analysis, and Raman spectroscopy. The degree of graphite oxidation was controllable ...

Synthesis of graphene nanoflakes by grinding natural ...
Natural graphite is a soft material that conventional milling methods fail to grind into nanoparticles. We found that adding NaCl into graphite during milling allows obtaining graphene nanoflakes of about 50×200nm 2 as evidenced by Transmission Electron Microscope (TEM). NaCl particles are substantially brittle and harder than graphite, serving as milling agents by both helping to chop ...

graphite ore ball mill
Ball milling of graphite with appropriate stabilizers is another mode of exfoliation in liquid phase. 21 Graphite is ground under high sheer rates with millimetersized metal balls causing exfoliation to graphene (Fig. ) under wet or dry instance this method can be employed to produce nearly 50 g of graphene in the absence of ...

Graphite functionalization by ball milling with sulfur ...
After shortterm milling (, after 10 min, blue curves in Fig. 1 A, B) 002 and 004 reflections, corresponding to crystal planes parallel to the graphitic planes, become definitely more intense than for the starting graphite (black curves in Fig. 1 A, B). This result can be rationalized by considering that short term milling induces an orientation of graphite platelets that is preferentially ...
