Abnormal p‐type Gas‐Sensing Response to Ether in Co‐ZnO Nanocomposite Film and Its Significant Room‐Temperature Magnetoresistance

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

Published: Jan. 19, 2025

Abstract As a remarkable gas‐sensing material, ZnO is limited by the gas selectivity of its indiscriminate response to multiple gases. Herein, abnormal p‐type responses ether but n‐type othervolatile organic compoundsare observed in Co‐ZnO nanocomposite films. It should be attributed inversion region at particle interface, on which tends selectively adsorb. By controlling Co content, nanoflower structure realized, significantly increases adsorption sites and enhances eight times that film. Dual‐mode output based chemiresistive magnetoresistance offers another way improve selectivity. To this point, dual‐response granular film constructed with superficial 3 O 4 ‐ZnO p‐n heterojunction internal superparamagnetic conduction path. The high saturation magnetization 2990 Gs realized 26 at.% Co. P‐type resistance variation 12% room‐temperature ‐7% are simultaneously achieved.

Triethylamine Sensing Behavior of P-Lafeo3/N-Zno Composite Synthesized by One-Step Hydrothermal Method

Published: Jan. 1, 2025

The emission of triethylamine presents a significant hazard to both human health and environmental safety, making the development highly effective gas sensor specifically for detecting (TEA) crucial. In this paper, we prepared six sensors using one-step hydrothermal method by controlling proportion Zn. Among them, S4 (LaFeO3/ZnO 1:0.5) exhibited most outstanding sensing properties, including lower operating temperature (200℃), high selectivity, low detection limit (35.6 ppb), good repeatability, faster adsorption/desorption time (38 s/35 s), higher response value (Response=50), excellent long-term stability. construction p-n heterojunction, rough porous surface, increased oxygen vacancies specific surface area endow composite material with superior characteristics. This work confirms that formation heterojunctions is an strategy enhancing performance.
