摘要

氢传感在清洁能源技术中的作用至关重要。本文首次提出了一种基于局部表面等离子体共振（LSPR）的高效传感器--银-钯-金三元胶体系统，用于在水环境中传感 H2。接触 H2 后，该系统在短短 10 分钟内就出现了 42 nm 的显著 LSPR 峰值移动，而在相同条件下对 N2 则无明显反应。

Aqueous phase Localized Surface Plasmon Resonance based Hydrogen sensing using Mixed colloidal Ag and PdAu nanoparticles

Hydrogen sensing is critical for its role in clean energy technologies. Herein, a colloidal Ag-PdAu ternary system as an efficient Localized Surface Plasmon Resonance (LSPR)-based sensor is first proposed for H₂ sensing in aqueous environments. Upon exposure to H₂, the system exhibits a significant LSPR peak shift of 42 nm within just 10 min, with no observable response to N₂ under identical conditions.
