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).
