This study explores
the production of flash graphene (AC-FG) from
anthracite coal by using the flash Joule heating (FJH) method. This
study demonstrates that AC-FG can be derived from anthracite coal
by precisely controlling the system parameters, specifically the pulse
voltage. The FJH process requires no catalyst. The produced material
was characterized by using Raman, XRD, XPS, TG, SEM, TEM, and XPS
techniques. The results reveal that the degree of graphitization of
coal reaches its peak at 190 V. From an energy perspective, FJH provides
a straightforward and cost-effective method for graphene preparation,
offering a substantial avenue for the efficient utilization of coal
resources and the cost-effective application of graphene.
