摘要

In this work, a dual-functional electrochemical sensor has been proposed based on Sn-doped defective Bi2S3 (TDDB) microspheres, which exhibited the excellent electrochemical performance on Pb(II) and H2O2 detection. The TDDB offered a satisfied detection limit of 8.0 nM towards Pb(II) with a sensitivity of 96.7 mu A . mu M-1. As a H2O2 sensor, a high sensitivity of 3540 mu A mM(-1) cm(-2) was obtained in a linear range from 0.45 mM to 10 mM with a detection limit of 10 nM. Moreover, the electrochemical detection of Pb(II) in Taihu Lake and H2O2 in human serum was achieved with high reliability and good recovery.
