▎ 摘　　要

NOVELTY - Producing two-dimensional nano-materials, comprises (a) providing a mixture (a1) containing e.g. graphene oxide particles, and at least a cationic and/or non-ionic surfactant or a mixture (a2) containing e.g. graphene particles, and at least a cationic and/or non-ionic surfactant, (b) adding at least a sol precursor compound to the mixture of step (a), (c) allowing the mixture of step (b) to react in a sol-gel process for forming a gel, (d) removing the surfactant and (e) optionally heating the graphene oxide particles coated with gel to reduce the graphene oxide to graphene. USE - The method is useful for producing two-dimensional nano-materials (claimed), which are useful in catalysts, sensors, capacitors, and primary and secondary electrochemical cells and fuel cells. ADVANTAGE - The method provides nano-materials with high yield. DETAILED DESCRIPTION - Producing two-dimensional nano-materials, comprises (a) providing a mixture (a1) containing graphene oxide particles, water and at least a cationic surfactant and/or non-ionic surfactant or a mixture (a2) containing graphene particles, at least a solvent for chemically splitting graphite, and at least a cationic surfactant and/or non-ionic surfactant, (b) adding at least a sol precursor compound to the mixture of step (a), (c) allowing the mixture of step (b) to react in a sol-gel process for forming a gel from the sol precursor compound on the graphene oxide particles or the graphene particles, (d) removing the surfactant and (e) optionally heating the graphene oxide particles coated with gel for at least 1 minute at at least 500 degrees C in an inert gas atmosphere in order to reduce the graphene oxide to graphene.
