The present study focuses on correlations between three parameters: (1) graphite particle size, (2) the ratio of to oxidizing agent (KMnO4), and (3) acid (H2SO4 H3PO4), with reaction yield, structure, properties graphene oxide (GO). are a challenge, as these parameters can hardly be separated from each other due variations in viscosity system. larger particles, higher GO. Decreasing KMnO4 1:4 1:6 generally leads degree oxidation yield. However, differences very small. Increasing graphite-to-acid-volume 1 g/60 mL g/80 mL, except for smallest reduced slightly yield mainly depends extent purification GO by water, not conditions. large thermal decomposition bulk size less parameters.
