Well-Arranged Porous Co3O4 Microsheets and Its Electroanalysis toward Pb (II)

Zhong-Gang Liu and Xing-Jiu Huang
Abstract—Well-arranged porous Co3O4 microsheets has been successfully synthesized via a hydrothermal process and subsequent thermal decomposition. The characterization of the as-prepared product is identified with scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM) and X-ray diffraction (XRD). The results show that the as-prepared porous Co3O4 possesses the face-centered cubic phase structure and well single-crystallized phase. Its electrochemical performance was characterized with square wave anodic stripping voltammetry (SWASV) for the detection of Pb(II) at the porous Co3O4/nafion modified electrode with the good sensitivity of 48.5 μA·μM-1 and detection limited of 30 nM (3σ method). In addition, the stability measurement is investigated under the optimized conditions.

Index Terms—Porous Co3O4 microsheets, hydrothermal process, heavy metal ions, electroanalysis.
