Exposure to mustard gas can cause damage or death human beings, depending on the concentration and duration. Thus, developing high-performance mustard-gas sensors is highly needed for early warning. Herein, ultrathin WO3 nanosheet-supported Pd nanoparticles hybrids (WO3 NSs/Pd) are prepared as chemiresistive sulfur simulant (e.g., 2-chloroethyl ethyl sulfide, 2-CEES) sensors. As a result, optimal NSs/Pd-2 (2 wt % of Pd)-based sensor exhibits high response 8.5 rapid response/recovery time 9/92 s toward 700 ppb 2-CEES at 260 °C. The detection limit could be low 15 with 1.4. Moreover, shows good repeatability, 30-day operating stability, selectivity. In NSs/Pd-2, NSs rich in oxygen vacancies, offer more sites adsorb species, make their size close even within thickness so-called electron depletion layer, thus inducing large resistance change (response). strong metal–support interactions (SMSIs) between enhance catalytic redox reaction performance, thereby achieving superior sensing performance 2-CEES. These findings this work provide new approach optimize by constructing SMSIs metal oxides.

Abstract The transition toward hydrogen gas (H 2 ) as an eco‐friendly and renewable energy source necessitates advanced safety technologies, particularly robust sensors for H leak detection concentration monitoring. Although palladium (Pd)‐based materials are preferred their strong affinity, intense palladium–hydrogen (Pd–H) interactions lead to phase transitions hydride (PdH x ), compromising sensors’ durability speeds after multiple uses. In response, this study introduces a high‐performance sensor designed from thiolate‐protected Pd nanoclusters (Pd 8 SR 16 which leverages the synergistic effect between metal protective ligands form intermediate palladium–hydrogen–sulfur (Pd–H–S) state during adsorption. Striking balance, it preserves Pd–H binding affinity while preventing excessive interaction, thus lowering required desorption. dynamic adsorption‐dissociation‐recombination‐desorption process is efficiently highly reversible with , ensuring rapid sensing at parts per million (ppm). ‐based demonstrates exceptional stability (50 cycles; 0.11% standard deviation in response), prompt response/recovery (t 90 = 0.95 s/6 s), low limit of (LoD, 1 ppm), ambient temperature operability, ranking among most sensitive Pd‐based sensors. Furthermore, multifunctional prototype practicality real‐world using ligand‐protected nanoclusters.
