Advances in electrochemical sensing with ZIF-67 and related materials

ZIF-67, a novel zeolitic imidazolate framework material composed of Co ions and imidazolate ligands, has de-volved as a widely concerned material for electrochemical sensing due to its outstanding characteristics such as attractive topological structure, both redox metal active site and organic functional groups. To date, it is still highly expected to develop new significant materials for electrochemical sensing based on ZIF-67. Here, an overview of ZIF-67 and related materials in electrochemical sensor is just in time. During last decade, in couple of reviews describing the overview of various applications of metal-organic frameworks (MOFs) materials in the field of electrochemical sensors, there are some scattered reports about ZIF-67 and related materials. For the first time, this article reviews the latest applications and research progress of ZIF-67 and its related materials in electrochemical sensor, focusing on the following three types of electrode modification materials: (1) ZIF-67, functionalized ZIF-67 and ZIF-67 composites, (2) ZIF-67 derived Co3O4 porous polyhedrons, (3) ZIF-67 derived porous carbon polyhedrons. Finally, some perspectives on the potential future research directions and appli-cations for ZIF-67 and its related materials are offered.
