Selective Detection of H₂ Gas in Gas Mixtures Using NiO‐Shelled Pd‐Decorated ZnO Nanowires (Adv. Mater. Technol. 13/2024)

H2 Gas Detection In article number 2302081, Mikhael Bechelany, Lionel Santinacci, Hyoun Woo Kim, Sang Sub Kim, and co-workers describe the development of a highly sensitive and selective H2 gas sensor. This sensor utilizes ZnO nanowires (NWs) decorated with Pd nanoparticles (NPs) and a NiO shell layer, all deposited via atomic layer deposition. This sensor demonstrates high sensitivity and selectivity to H2 gas even in the presence of H2/CO and H2/NO2 gasmixtures, offering potential for highly selective H2 gas detection.
