Nonaqueous Synthesis of Pd/PdO-Functionalized NiFe2O4 Nanoparticles Enabled Enhancing n-Butanol Detection

Nanomaterials, Journal Year: 2024, Volume and Issue: 14(14), P. 1188 - 1188

Published: July 12, 2024

The efficient detection of n-butanol, which is in demand for highly sensitive materials, essential multiple applications. A nonaqueous method was applied to prepare NiFe2O4 nanoparticles (NPs) using benzyl alcohol as a solvent, shows size 7.9 ± 1.6 nm and large surface area 82.23 m2/g. To further improve the sensing performance Pd/PdO functionalization sensitized with NPs. Gas results demonstrate that Pd/PdO-NiFe2O4 exhibits an enhanced response 36.9 300 ppm n-butanol fast recovery time (18.2/17.6 s) at 260 °C. Furthermore, Pd/PdO-NiFe2O4-based sensor possesses good linear relationship between responses concentration from 1 1000 ppm, great selectivity against other volatile organic compounds (VOCs). excellent enhancement attributed catalytic effects Pd/PdO, increase oxygen vacancies, formation heterojunction PdO NiFe2O4. Thus, this study offers effective route synthesis Pd/PdO-functionalized NPs achieve performance.

The field of gas sensors has been developing for the last year due to necessity characterizing compounds and, in particular, volatile organic whose detection can be special interest a vast range applications that extend from clinical evaluation environmental monitoring. Among all potential techniques develop sensors, magnetron sputtering emerged as one most suitable methodologies production large-scale uniform coatings, with high packing density and strong adhesion substrate at relatively low temperatures. Furthermore, it presents elevated deposition rates, allows growth thin films purity, permits precise control film thickness, enables simple manufacturing power consumption consequently, costs involved production. This work reviewed current developed through VOCs assessment by gathering relevant scientific works published. A total 10 were considered this work. Additionally, 13 other identified promising targets classified future trends field. Overall, summarizes state-of-the-art technology, allowing community take step forward explore new research areas.
