▎ 摘　　要

NOVELTY - Large-scale quantities of graphite oxide, graphene oxide, and/or graphene are produced by ultrafine grinding graphite ore, carrying out flotation purification of graphite ore in bi-distilled water at less than or equal to 90 degrees C, performing graphite oxidative transformation of graphite oxide, separating and/or purifying graphite oxide, obtaining graphene oxide from graphite oxide, and obtaining graphene from graphene oxide at less than or equal to 200 degrees C, preferably less than or equal to 100 degrees C. USE - An industrial method of producing large-scale quantities of graphite oxide, graphene oxide, and/or graphene for use as catalysts and in microelectronics and energy storage (all claimed). ADVANTAGE - The method can be employed without the additional step of controlling for particle size, objects uses readily available, naturally-occurring, and relatively affordable graphite ore, and has low harmful effects on the environment and human health. DESCRIPTION OF DRAWING(S) - The drawing shows a flow-diagram of the sequential order of producing large-scale quantities of graphite oxide, graphene oxide, and/or graphene.
