Abstract

Hydrogen has become as a significant energy source. Nonetheless, its threat of explosion poses a challenge to the production and use of hydrogen. This study employs electron beam evaporation technology to produce the Ag-Pd multilayer composite plasmonic hydrogen sensors (PHS), which fulfills the requirement for hydrogen safety detection. The sensing characteristics of monolayer, double-layer and multilayer metal film arrays are systematically compared. The excited local surface plasmon resonance (LSPR) on the multilayer composite films enhance the signal intensity effectively. At the same time, the hot spots area excited by the electric field provide energy for hydrogen adsorption, which synergically promotes the fast response of hydrogen. The PHS based on the Ag-Pd multilayer composite films array has the advantages of fast response, high sensitivity and low detection limit. The multilayer composite plasmonic hydrogen sensing platform developed provides an important theoretical basis and technical support for the development of high-performance hydrogen sensors.
