摘要
三乙胺（TEA）环境暴露会对人体健康造成一系列损害。因此，在工业和环境安全中，对TEA检测的高响应和快速响应有着重要的要求。本文描述了一种修饰金属有机骨架（MOF）衍生ZnO纳米粒子的银纳米粒子（NPs），并进一步探讨了其茶传感性能。研究了ZnO表面载银量对ZnO结构形貌、晶粒尺寸和位错密度的影响。有趣的是，相关的传感测试表明，使用1.3 mol% Ag NPs/ZnO制备的气体传感器在225℃的最佳温度下检测TEA时，具有出色的交叉响应，性能高（Ra/Rg = 430.6-100 ppm），检测浓度低（1 ppm），响应和恢复时间短（9/49 s）。该TEA响应结果远优于最近的报告。此外，从结构优势和Ag nps引入效应两方面分析了该ZnO表面的表观tea传感能力。本文为基于贵金属修饰mof衍生氧化物设计高响应传感器开辟了一条新途径。
Ag nanoparticle-decorated MOF-derived ZnO nanoparticles for apparent and rapid response towards triethylamine vapor
The exposure of triethylamine (TEA) environment can cause a series of damage to the health. Therefore, the high and fast response for TEA detection is significantly required in the industrial and environmental safety. In this paper, a kind of Ag nanoparticles (NPs) decorated metal-organic framework (MOF)-derived ZnO nanoparticles has been described and further explored its TEA-sensing performance. The influence of the Ag-loaded contents over ZnO surface on the structural morphology, crystal size, and dislocation density is investigated in detail. Interestingly, the related sensing tests show the as-prepared gas sensor using 1.3 mol% Ag NPs/ZnO exhibits an outstanding cross-response, high capability (Ra/Rg = 430.6–100 ppm), low detection concentration (1 ppm), along with short response and recovery time (9/49 s), when detecting TEA at the optimal temperature of 225 °C. And this TEA response result is far superior to those of the recent reports. Moreover, the apparent TEA-sensing ability is analyzed from the structural advantage and Ag NPs-introducing effect over this ZnO surface. This article opens a new avenue to design high-responsive sensor based on noble metal-modified MOF-derived oxides.
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.
