Amorphous PdRuO_x as High-Activity Sensitizers for Ultrafast Low-Humidity Sensors

ACS Sensors, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 3, 2025

Amorphous noble metals often display excellent sensitization due to their unsaturated atomic coordination and abundant active sites on the surface. In this work, amorphous palladium-ruthenium bimetallic nanoparticles were successfully prepared by lithium doping incorporated into MOF-303 using a confinement strategy. Compared with crystalline c-PdRuOx@MOF-303, low-humidity sensor constructed a-PdRuOx@MOF-303 exhibits higher response values (3600 Hz 3.39% RH), shorter response/recovery time (9/7 s), hysteresis (0.16% RH) stability. Meanwhile, has been further explored achieve continuous monitoring of human breathing, cough, finger humidity, providing broad application prospects for materials in wearable medical devices noncontact human-machine interactions. Additionally, sensitive mechanism was GCMC methods. The simulation results demonstrate that introducing a-PdRuOx pores leads significant enhancement adsorption properties. This improvement is not only tothe increase provided but also substantial rise energy hydrophilic pocket MOF-303. increases from -25.70 -31.56 kJ/mol, highlighting work synergy enables activation more water molecules, effectively enhancing overall capacity performance

Published: March 11, 2025

Abstract Flexible sensing electronics, with good lightweight and flexibility, can maintain excellent capability while fitting complex curved surfaces, having important applications in wearable devices, medical health monitoring, robotics. The rapid advancement of metal‐organic frameworks (MOFs) has created the prospect additional improvements flexible sensors. porous structure brings them a high specific surface area, meaning that when used as sensitive materials for sensors, sensitivity selectivity be achieved. Meanwhile, performance stability MOF‐based sensors further enhanced by modifying MOFs’ or compounding other materials, which is crucial manufacturing utilized working conditions. Herein, MOFs systematically reviewed. First, common series MOFs, preparation modification methods, highly conductive are introduced. application then expounded, including self‐powered mechanical sensing, gas liquid analyte multi‐target/mode sensing. It believed better response capabilities developed processes advance, expected to more widely future promote development technologies such human‐computer interaction technology.
