- Аннотация: This paper is devoted to a detailed study of the electrochemical intercalation of sulfuric acid into the foil structure based on thermally expanded graphite, as the decisive stage in the process of producing electrochemical graphene oxide. In the work, the potentials of individual areas of anodic polarization were determined, passing without destroying the carbon electrode. The diffusion control characteristic of the entire range of intercalation potentials is shown.The effectivecapacities, characteristictimes, andacid consumptionfor the electrochemical intercalationprocessareevaluated.Theminimum terminationpotentialoftheintercalationprocessisfound.Itisshownthatlimiting theanodicpolarizationofthermallyexpandedgraphiteattheminimumpotentialfortheterminationofintercalation cansignificantlyreducetheenergyconsumptionoftheentiremethodforproducingelectrochemicalgrapheneoxide.A comparison is made of electrochemical graphene oxide with graphene oxide, obtained by a modified Hammers method, bya number of physicochemical methods.
