Abstract
AbstractIn 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 μM–4.6×103 μM), a detection limit as low as 0.26 μM, a high sensitivity (307.5 μA 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.
