Mitigating the Pd─H Binding Trade‐Off Through High‐Entropy Alloying for Enhancing the Performance of SnO 2 Sensors

Heyu Wang, Ou Wang, Yu Tang, Wenxiu Xiao et autres

ABSTRACT As an effective sensitizer for chemiresistive hydrogen (H 2 ) sensors, the practical application of Palladium (Pd) is limited by the Sabatier principle, where intrinsically strong Pd─H binding leads to sluggish desorption kinetics and prolonged response and recovery time. A high‐entropy …

Overcoming the Sensitivity‐Selectivity Trade‐Off in Chemiresistive CO Sensors Through a Single‐Atom Pt‐Activated Lattice Oxygen Strategy

Pengfei Li, Leiyu Diao, Ou Wang, Longfei Li et autres

ABSTRACT The sensitivity‐selectivity trade‐off remains a fundamental challenge in chemiresistive carbon monoxide (CO) sensing, as enhanced surface redox activity often promotes non‐specific reactions with chemically similar interferents. Single‐atom noble‐metal sensitizers improve adsorption selectivity but suffer from ultra‐low loading, limiting sensing sensitivity. Here, …

Electron‐Deficient Pd Enabled by Single‐Atom Alloy Drives Fast and CO‐Resistant Hydrogen Sensing

Ou Wang, Leiyu Diao, Pengfei Li, Youyou Feng et autres

ABSTRACT Pd‐based nanoparticles have been widely employed to enhance H 2 sensing performance due to their strong capability for H 2 adsorption and dissociation. However, strong Pd–H* interactions hinder the hydrogen spillover process, while pronounced CO adsorption results in poor selectivity. Herein, …
