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 storageeninfo:eu-repo/semantics/closedAccessArticle375466212-s2.0-85166778898N/AWOS:001033138100001Q2
