A novel triethylamine gas sensor based on PrVO4 material by hydrothermal synthesis
Triethylamine (TEA) is a colorless, oily organic compound that can cause serious harm to humans and the environment. Therefore, it is crucial to develop a gas sensor that can rapidly detect TEA. Rare earth vanadate has attracted much attention in the field of sensors due to their strong catalytic effect, good crystallization and chemical stability. In this work, PrVO4 nanorods were synthesized by hydrothermal method. The crystal structure and morphology of PrVO4 were characterized by XRD, SEM, TEM and SAED. The novel PrVO4 gas sensor exhibits excellent gas sensitivity to TEA at 230 °C, including low concentration detection capability, fast adsorption/desorption times (19 s/14 s), good repeatability and long-term stability. In addition, the gas-sensitive mechanism of PrVO4 is briefly discussed. Therefore, PrVO4 can be used as a novel gas-sensitizing material.
期刊介绍：
Vacuum is an international rapid publications journal with a focus on short communication. All papers are peer-reviewed, with the review process for short communication geared towards very fast turnaround times. The journal also published full research papers, thematic issues and selected papers from leading conferences.
A report in Vacuum should represent a major advance in an area that involves a controlled environment at pressures of one atmosphere or below.
The scope of the journal includes:
1. Vacuum; original developments in vacuum pumping and instrumentation, vacuum measurement, vacuum gas dynamics, gas-surface interactions, surface treatment for UHV applications and low outgassing, vacuum melting, sintering, and vacuum metrology. Technology and solutions for large-scale facilities (e.g., particle accelerators and fusion devices). New instrumentation ( e.g., detectors and electron microscopes).
2. Plasma science; advances in PVD, CVD, plasma-assisted CVD, ion sources, deposition processes and analysis.
3. Surface science; surface engineering, surface chemistry, surface analysis, crystal growth, ion-surface interactions and etching, nanometer-scale processing, surface modification.
4. Materials science; novel functional or structural materials. Metals, ceramics, and polymers. Experiments, simulations, and modelling for understanding structure-property relationships. Thin films and coatings. Nanostructures and ion implantation.
