摘要
In this paper, we report the preparation of an SnO2/TiO2 nanocomposite (SnO2/TiO2 NC) for modifying a glassy carbon electrode (GCE) via a self-assembly approach; the SnO2/TiO2/GCE thus prepared was employed as a working electrode for the electrochemical detection of hydrazine (Hz) at room temperature. The detection of Hz as a model analyte was efficiently monitored by the dual approaches of linear sweep voltammetry and cyclic voltammetry under different optimization conditions. The SnO2/TiO2/GCE sensor showed a low limit of detection (LoD), and high sensitivity and selectivity with good linearity. The sensitivity and LoD of the proposed sensor were obtained using CV as 23.14 mu A mu M-1 cm(-2) and 0.160 mu M, respectively. A linear calibration plot was obtained (R-2 = 0.974) for varying concentrations of Hz (5 to 45 mu M). However, the sensitivity and LoD using LSV were obtained as 32.92 mu A mu M-1 cm(-2) and 0.143 mu M, respectively with linear range of 1 to 40 mu M (R-2 = 0.984). The present work provides a method of fabrication of an SnO2/TiO2 NC-based electrochemical sensor that is effective in the detection of hazardous chemicals.
