▎ 摘　　要

NOVELTY - Producing multilayered heterostructure, comprises (a) mixing graphene oxide nanosheets, polydiallyldimethylammonium chloride and hydrazine to prepare a graphene oxide nanosheet having modified surface with poly diallyldimethylammonium chloride (PDDA), and (b) immersing the modified graphene oxide nanosheets in a colloidal solution in which ruthenium oxide and molybdenum disulfide are mixed in a weight ratio of 1:4-6. USE - The method is useful in producing multilayered heterostructure for producing catalyst. ADVANTAGE - The method is simple, and produces repeatedly stacked heterostructure having excellent electrochemical catalytic properties, high electrochemical properties and hybrid conductive layer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for multilayered heterostructure produced by the above method.
