Richly Ionized 2D HOF Membranes Enable Efficient Humidity Sensing

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 26, 2025

Abstract Current humidity sensors often underperform due to the limited availability of moisture‐sensitive active sites within their material substrates, as well ineffective ion transport properties. Here, a new approach is presented using richly ionized 2D hydrogen‐bonded organic frameworks (HOFs) membranes, which feature high density pores and wide network continuous binding for water molecules. To significantly enhance sensing performance, cationic nanoconfined strategy employed. This involves nanoscale doping, modifies interlayer spacing HOFs, thereby revealing more hydrophilic providing additional ions improve conductivity. Based on these advancements, highly adjustable flexible sensor equipped with asymmetrical MXene electrodes developed. demonstrates rapid response/recovery times 0.42/0.62 s, an ultra‐high on/off ratio 3.5 × 10 4 , remarkable stability over than 200 cycles. The electrical performance system driven by potential difference between electrodes, rather electrode materials themselves, allowing increased versatility scalability. development offers pathway featuring enhanced ionic conductivity improved non‐contact capabilities.

Ag-doped capsule-like tungsten oxide with controllable band structure and oxygen vacancy for highly efficient triethylamine sensing

Applied Physics Letters, Journal Year: 2025, Volume and Issue: 126(13)

Published: March 1, 2025

The detection and portable monitoring of organic amine is necessary for hazardous substance warning, life, health. Herein, capsule-like tungsten oxide nanoparticles (NPs) were prepared to detect triethylamine, the gas-sensing property further enhanced by adjusting oxygen vacancy band structure doping with Ag NPs. As-prepared nanomaterial consists well-dispersed shapes. More chemically adsorbed are formed in Ag-doped oxide, bandgap decreases compared pristine oxide. tests show that optimal (Ag/WO3) NPs-based sensor exhibits more than six times response higher toward 50 ppm triethylamine (TEA) at an temperature 220 °C, a limit as low 248 ppb. Notably, fast recovery time anti-interference properties remarkable, two-week stability also satisfactory, which superior reported related materials. For real-time TEA detection, as-prepared Ag/WO3 proved be efficient sensing material applications.
