Abstract

Abstract In this work, highly dispersed Pt nanoparticles (PtNPs) were deposited on the surface of the TiO₂ nanosheets (TiO₂NSs) by the photodeposition method in the presence of methanol as holes scavengers. The results indicated that PtNPs were distributed on TiO₂NSs successfully with the diameter of ca. 5-9 nm. The electrochemical experiments such as electrochemical impedance spectroscopy and cyclic voltammetry were used to study the electrochemical properties of the PtNPs/TiO₂NSs modified glassy carbon electrode (GCE). The as-prepared PtNPs/TiO₂NSs/GCE presents excellent electrocatalytic activity for hydrazine. The sensor can be used to determine hydrazine at low potential with a wide linear range, high sensitivity, and fast response time. Moreover, the sensor exhibits good selectivity and reproducibility. In addition, the recoveries were 100.1-105.3% for hydrazine in the tap water, indicating the PtNPs/TiO₂NSs/GCE should be a promising sensor for the determination of hydrazine in real samples.
