| Popis: | Recently, the design of biomimetic enzymes based on ultrathin two-dimension (2D) metal-organic framework (MOF) nanosheets have attracted great attention due to their large surface area and abundant accessible active sites. In this work, ultrathin 2D MOF nanosheets and multi-walled carbon nanotubes (MWCNTs) are simply mixed to prepare the composite (2D MOF/MWCNT) films though a Langmuir–Schafer method. The 2D MOF/MWCNT films are easily transferred on electrodes as a novel electrochemical platform for the detection of hydrogen peroxide (H2O2), with a detection limit of 0.70 μM (S/N = 3), a wide linear range from 0.001 to 8.159 mM, a high sensitivity of 157 μA cm−2 mM−1, a short response time of |
