▎ 摘  要

NOVELTY - Manufacture of highly-ordered mesoporous graphene material involves adding hydrophilic solvent and fluoroboric acid or nitrosonium tetrafluoroborate to iron tetroxide nanoparticles colloidal solution, stirring, centrifuging, evaporating solvent to form highly-ordered nanoparticles superlattice, calcining superlattice at high temperature under an argon or nitrogen atmosphere to obtain carbon-coated iron oxide nanoparticles superlattice material, dispersing the carbon-coated iron oxide nanoparticles superlattice material in strong acid, and etching to remove iron oxide nanoparticles. USE - Manufacture of highly-ordered mesoporous graphene material used for lithium-ion battery, supercapacitor and gas sensor. ADVANTAGE - The method enables efficient manufacture of mesoporous carbon material with controlled thickness, large surface area and excellent structural stability, by simple method. DETAILED DESCRIPTION - Manufacture of highly-ordered mesoporous graphene material involves mixing iron oleate, and oleic acid or oleylamine, heating, coating iron oxide nanoparticles with the mixed solution, dispersing coated iron oxide nanoparticles in non-polar solvent to form stable iron tetroxide nanoparticles colloidal solution, adding hydrophilic solvent, carbon-containing compound and fluoroboric acid or nitrosonium tetrafluoroborate, stirring, centrifuging, evaporating solvent to form highly-ordered nanoparticles superlattice, calcining the superlattice at high temperature under an argon or nitrogen atmosphere to obtain carbon-coated iron oxide nanoparticles superlattice material, dispersing the carbon-coated iron oxide nanoparticles superlattice material in a strong acid, and etching to remove iron oxide nanoparticles.
