A new lanthanide metal–organic framework,[La(BTC)(H2O)(DMF)] was synthesized under hydrothermal conditions and were characterized by scanning electron microscopy in combination with energy dispersive X-ray spectroscopy (SEM/EDX),X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FI).Electrochemical sensing features were studied by electrochemical impedance spectroscopy and cyclic voltammetry (CV).The cyclic voltammogram of [La (BTC) (H2O) (DMF)] show a pair of redox peaks at ca.-0.7 V in 0.1 M pH 7.0 PBS which corresponds to LaⅢ(OH)-MOF/LaⅡ(H2O)-MOF *** La-MOF nanomaterials show high electrocatalytic activity towards H2O2.A linear range is from 0.5 μM to 8 μ***,La-MOF is a promising material for H2O2 detection.
