Abstract

Herein, an electrochemical sensor for the detection of H2O2 based on nafion glassy carbon electrode modified with MIL101(Cr) and nano-MIL101(Cr) are developed and its electrochemical characterizations analyzed by CV and CA. In comparison with the NGCE, MIL101/NGCE and nano-MIL101/NGCE, the nano-MIL101/NGCE showed a sharp redox peak specific to H2O2 was obtained in the phosphate-calibrated solution. nano-MIL101/NGCE exhibited good linear response in terms of the relationship between peak currents and concentrations as from 0 to 650 mu M (R-2=0.99), with a low limit of detection 3.8 mu M, high sensitivity 986 mu A mM(-1) cm(-2) and nano-MIL101/NGCE exhibited ideal repeatability, reproducibility, stability and the interference-free perception of H2O2.
