摘要

食品腐败导致大量浪费，并构成严重的健康风险，但在整个供应链和存储过程中，实时监测解决方案仍然有限。在此，我们开发了一种基于Pt/ fe - tin的燃料电池气体传感器，用于高灵敏度和选择性检测硫化氢（H2S），硫化氢是肉类腐败的关键指标。在TiN中掺入Fe可以有效调节Pt的电子结构，提高H2S的灵敏度，减轻湿度干扰。Pt/Fe-TiN传感器达到100 ppb的检测极限，即使在- 18°C下也能保持完全工作。与商用Pt/C电极相比，它具有优越的稳定性，在高湿条件下60天后仍能保持97%以上的灵敏度。此外，开发了一种集成智能手机接口的实时H2S监测设备，用于肉类储存中的连续腐败检测。这项工作为食品安全监测提供了一个实用的实时传感平台，有助于减少浪费和提高供应链透明度。

Robust H2S Sensing with Pt/Fe-TiN Fuel Cell Sensors for Cold-Chain Meat Spoilage Monitoring

Food spoilage leads to significant waste and poses serious health risks, yet real-time monitoring solutions remain limited throughout the supply chain and storage. Herein, we develop a Pt/Fe-TiN-based fuel cell gas sensor for highly sensitive and selective detection of hydrogen sulfide (H₂S), a key indicator of meat spoilage. Fe doping in TiN effectively modulates the electronic structure of Pt, enhancing H₂S sensitivity and mitigating humidity interference. The Pt/Fe-TiN sensor achieves a detection limit of 100 ppb and remains fully operational even at −18 °C. Compared to commercial Pt/C electrodes, it exhibits superior stability, retaining over 97% of its sensitivity after 60 days under high humidity. Furthermore, a real-time H₂S monitoring device integrated with a smartphone interface was developed for continuous spoilage detection in meat storage. This work provides a practical, real-time sensing platform for food safety monitoring, contributing to reduced waste and improved supply chain transparency.
