Due to the important role of hydrogen peroxide (H2O2) in biological systems and its wide range of practical applications, the development of efficient electrochemical H2O2 sensors has become a highly attractive research area. Herein, we reports the synthesis and fabrication of zinc-based coordination polymer Zn(bim)(L1)(Cl)]n (CP-a): bim = 1-benzylimidazole, L1 = terephthalic acid] on modified carbon paste electrode (CP-a/CPE) for the electrochemical detection of H2O2. The surface morphology of CP-a/CPE was confirmed by field emission scanning electron microscopy. Electrochemical sensing features were evaluated by cyclic voltammetry and chrono-amperometry. The linear range at the potential of -0.5 V based on CP-a/CPE for H2O2 was 0.001 mM-60 mM, with a low detection limit (LOD) of 0.0004 mM. The effect of interfering species on the reduction peak current response shows a minor change of signals (>5%). The as-synthesized CP-a/CPE sensor exhibited efficient reproducibility and stability. The electrocatalytic activity and good performance imply that the metal-based coordination polymers are potential candidates for fabricating electrochemical sensors.
