| dc.description.abstract | Metal−organicframeworks(MOFs)attracttheattentionof researchersdue to their uniqueproperties,such ashigh surfacearea, porosity,and stability.Therefore,in this study,the synthesisof zeoliticimidazoleframeworks(ZIF-8),a subclassof MOFs,and copperoxide (Cu2O) and manganeseoxide (MnO2)containingZIF-8was carriedout by a mixingmethodwithmethanol.The characterizationresultsshowthat the polyhedralstructureof ZIF-8was preparedwith a surfacearea of 2088 m2/gand a crystallitesize of 43.48nm. Then,each and mixtureof twometaloxideswere introducedinto the ZIF-8crystalstructure.Itwas foundthat the surfacearea and pore volumesof all metal/ZIF-8 samplesdecreasedwith metal loading,dependingon the type andratio of metal oxides.The ZIF-8containing4.0 wt % Cu2O and 1.0wt % MnO2had the highestsurfacearea (2084m2/g), whichwas closestto that of ZIF-8.The polyhedralstructurewas maintainedby the additionof both metal oxides,and the crystalsize of the materialdecreasedwith the loadingof MnO2to the ZIF-8structure.All of the synthesizedsampleswere analyzedin supercapacitorapplicationsand a relativelyhighervalue of specificcapacitancewasobtainedfor Cu−Mn/ZIF-8due to highersurfacearea and improvedconductivity.In additionto supercapacitorapplications,thepropertiesof metal/ZIF-8are also promisingfor applicationssuch as catalysts,membranes,and gas storage | tr |
