摘要

Epichlorohydrin (ECH) is mainly an industrial raw material, while it is toxic and dangerous for human health, so finding a simple and effective method for detecting ECH gas is challenging work. Porous SnO2 structures are successfully obtained through a hydrothermal method using SnCl4·5H2O as the tin source and water as the solvent. Ag nanoparticle (NPs) decorated porous SnO2 structures have also been prepared by the impregnation method. The morphology and structure of the as-prepared products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and the nitrogen adsorption–desorption technique. The as-synthesized nanostructures, with diameters ranging from 4–5 μm, are composed of porous nanosheets with an average thickness of 60 nm. The gas sensing properties of the Ag NPs decorated porous SnO2 structures for ECH gas were investigated in detail, and the results showed that the 10% Ag NPs decorated porous SnO2 structures gas sensor was the optimum sensor, demonstrating a response (S = 50) for 100 ppm of ECH gas, while the working temperature was decreased by about 180 °C. In addition, it showed a low detection level (0.5 ppm) for ECH gas, good reproducibility and repeatability, and long-term stability, implying a promising application in detecting ECH gas.

CrystEngComm is the forum for the design and understanding of crystalline materials. We welcome studies on the investigation of molecular behaviour within crystals, control of nucleation and crystal growth, engineering of crystal structures, and construction of crystalline materials with tuneable properties and functions. We publish hypothesis-driven research into… how crystal design affects thermodynamics, phase transitional behaviours, polymorphism, morphology control, solid state reactivity (crystal-crystal solution-crystal, and gas-crystal reactions), optoelectronics, ferroelectric materials, non-linear optics, molecular and bulk magnetism, conductivity and quantum computing, catalysis, absorption and desorption, and mechanical properties. Using Techniques and methods including… Single crystal and powder X-ray, electron, and neutron diffraction, solid-state spectroscopy, spectrometry, and microscopy, modelling and data mining, and empirical, semi-empirical and ab-initio theoretical evaluations. On crystalline and solid-state materials. We particularly welcome work on MOFs, coordination polymers, nanocrystals, host-guest and multi-component molecular materials. We also accept work on peptides and liquid crystals. All papers should involve the use or development of a design or optimisation strategy. Routine structural reports or crystal morphology descriptions, even when combined with an analysis of properties or potential applications, are generally considered to be outside the scope of the journal and are unlikely to be accepted.
