Simple and Green Approach Strategy to Synthesis Graphene Using Rice Straw Ash

초록

Abundant resources of rice straw and carbon-neutral have a lot of potentials to be converted into various value-added product and become more green due to less utilization of chemical usage. Graphene is one of value-added had been converted from rice straw and was successfully synthesized by using activating rice straw ash (RSA) using potassium hydroxide (KOH) at 700 oC with 1:2.5 impregnation ratio. scanning electron microscopy (SEM), field emission scanning electron microscopy (FESEM), EDX Analysis with a field emission transmission electron Microscope (FETEM) and atomic force microscopy (AFM). The current results can be the model for comparing the synthesize graphene from other plant sources. © Published under licence by IOP Publishing Ltd.
