Metal-organic frameworks-derived Zn-Ni-P nanostructures as high performance electrode materials for electrochemical sensing

[Display omitted] •MOF-derived bimetallic Zn-Ni-P nanostructures were fabricated by scalable and facile strategy.•The MOFs-derived Zn-Ni-P has flower-like structure that built from small 2D nanosheets.•These materials offer excellent electrocatalytic activity toward isoprenaline oxidation.•This superb electrocatalytic activity can be due to the synergistic effects and unique structures. The fabrication of hierarchical nanostructure based on metal–organic frameworks (MOFs)-derived transition-metal phosphides (TMPs) has become a hot topic in electrochemical sensor application owing to its unique properties. Herein, a scalable and facile strategy was proposed to prepare MOF-derived bimetallic Zn-Ni-P nanostructures. The material characterization showed that MOFs-derived Zn-Ni-P has flower-like structure that built from small 2D nanosheets. The MOFs-derived Zn-Ni-P was prepared via a facile phosphorization of Zn-Ni-MOF precursor in N2 atmosphere. This MOF-derived TMPs electrode materials offer excellent electrocatalytic activity toward isoprenaline (IPN) oxidation. In addition, the electrode shows wide two linear range (0.2 µM −5 mM and 5 mM-14 mM), short response time (
