Rational design of ZnO@ZIF-8 nanoarrays for improved electrochemical detection of H₂O₂

Abstract

Metal oxide nanostructures hold great promise in biosensors for non-enzymatic detection of H2O2. However the interfacial or morphology changes of metal oxides during electrochemical reactions due to corrosion greatly restricts...

MOF-Derived Tourmaline@ZnO Nanostructure as a High-Response Sensing Material of Gas Sensors toward n-Butanol

“…By assembling ZnIn 2 S 4 thin films on P-Ni-MOF-74 derived from Ni-MOF-74, ZnIn 2 S 4 /P-Ni-MOF-74 heterojunction with a diamond-shaped structure has been successfully constructed for efficient hydrogen evolution under visible light . The ZnO@ZIF-8 core–shell structure with excellent selectivity and long-term stability was synthesized by the hydrothermal growth of ZIF-8 on the ZnO surface for electrochemical sensing of H 2 O 2 . These great progresses were achieved because of the remarkable properties with selectable metal ion centers, multifunctional organic ligands, well-developed porosity, and diverse morphologies of metal–organic frameworks.…”

“…21 The ZnO@ZIF-8 core−shell structure with excellent selectivity and long-term stability was synthesized by the hydrothermal growth of ZIF-8 on the ZnO surface for electrochemical sensing of H 2 O 2 . 22 These great progresses were achieved because of the remarkable properties with selectable metal ion centers, multifunctional organic ligands, well-developed porosity, and diverse morphologies of metal−organic frameworks. ZIF-8 is a branch of MOF materials, usually the stable structure is rhombohedral dodecahedron, which has high chemical stability and thermal stability.…”
