摘要：

In this work, we reported the development of a nickel metal-organic framework nanosheet array on Ti-mesh (Ni-MOF/TM) as an enzyme-free electrochemical sensing platform for H2O2 determination. The as-obtained sensor exhibited outstanding detection properties of H2O2, which might be gifted from the large specific surface area, abundant active sites of Ni-MOF nanoarrays. The sensor displayed a good linear range (0.8 mu M-4.6x10(3) mu M), a detection limit as low as 0.26 mu M, a high sensitivity (307.5 mu A mM(-1) cm(-2)), and a rapid response. Moreover, this enzyme-free sensor is promising for point-of-care (POC) testing of H2O2 in human serum attribute to the excellent performance of Ni-MOF and the simple preparation process of the sensor.
