摘要

噻苯达唑（TBZ）和噻咪唑（thiram）是农业生产中广泛使用的杀菌剂，可有效防治病害。然而，它们在环境中的持续积累和迁移导致在土壤、地下水和其他基质中的过量残留，造成严重污染和重大的人类健康风险。本研究采用生态友好的化学方法合成了tio2 /PPy（聚吡咯）复合材料，建立了用于TBZ和thiram检测的光电化学（PEC）传感平台。导电PPy掺入显著提高了TiO₂的电荷分离效率，产生了显著的光电流响应（~ 6 μA/cm²）。所制备的PEC传感器对两种杀菌剂均具有可靠的检测性能。

One-step preparation of TiO2/PPy composite photoelectrochemical sensors and sensitive detection of TBZ and thiram

Thiabendazole (TBZ) and thiram are widely used fungicides in agricultural production for effective disease control. However, their persistent environmental accumulation and migration lead to excessive residues in soil, groundwater, and other matrices, causing severe contamination and significant human health risks. In this study, TiO₂/PPy (polypyrrole) composites were synthesized via an eco-friendly chemical method to develop a photoelectrochemical (PEC) sensing platform for TBZ and thiram detection. The conductive PPy incorporation significantly enhanced TiO₂'s charge separation efficiency, yielding a notable photocurrent response (∼6 μA/cm²). The fabricated PEC sensor demonstrated reliable detection performance for both fungicides.
