摘要
Cu2O/Cu nanoparticles(NPs)in the nanoporous carbon matrix(designated as Cu2O/Cu@NPC)has been synthesized by in-situ calcination of a cupper-based metal-organic framework(Cu-MOF),and its morphology and composition were characterized by PXRD,SEM and Raman.Furthermore,elemental mapping and XPS analysis not only show Cu NPs is generated along with nitrogen(N)-doped carbon,but also indicate Cu2O NPs locates in the external layer of Cu@NPC.In addition,the adsorption of dye studies implies that Cu2O/Cu@NPC exhibits obvious interaction with Rhodamine B(Rh B)due to the feature of porous and N-doped structure.Cu2O/Cu@NPC has highly electrocatalytic performance for glucose and mercury(Ⅱ)with wide detection range and good stability,which can be used as a novel multifunctional sensor for glucose and mercury(Ⅱ).
