Supraparticles for naked-eye H2 indication and monitoring: Improving performance by variation of the catalyst nanoparticles

Kailun Zhang et al.

Summary: The recent transition to H-2-based energy storage requires reliable and fast H-2 sensors for leak detection. In this study, we developed highly reactive gasochromic H-2 sensors based on the adsorption of H-2 on the material surface. The sensors showed a distinct and visible color change upon H-2 exposure, and the performance depended on the choice and size of the nanoparticle catalysts used. Among the materials tested, Pt-containing sensors demonstrated the best results for H-2 detection.

The role of H-H interactions and impurities on the structure and energetics of H/Pd(111)

K. Thurmer et al.

Summary: Understanding the incorporation of hydrogen into palladium requires a detailed understanding of the surface and subsurface structure and atomic interactions. Using density functional theory, the energies of hydrogen layers adsorbed on Pd(111) were examined. It was found that H-H and H-Pd interactions promote the formation of (root 3 x root 3) phases and an unreported (3 x 3) phase at high H coverages. Experimental evidence for the (3 x 3) phase was presented. The interaction between H and Pd is complicated by the presence of carbon at the surface, which reacts with hydrogen to form benzene.

Hydrogen-Induced Aggregation of Au@Pd Nanoparticles for Eye- Readable Plasmonic Hydrogen Sensors

Chao Li et al.

Summary: This study reports a new eye-readable H-2 sensor based on Au@Pd core-shell nanoparticle arrays. After exposure to 2% H-2, Au@Pd NAs show a significant decrease in optical extinction intensity and a color change due to H-2-induced aggregation of nanoparticles. The sensor performance is optimized by selecting appropriate substrates and adjusting the Pd shell thickness. This work highlights the advantage of designing eye-readable plasmonic H(2) sensors by tuning the interparticle plasmonic coupling in nanoparticle assemblies.
