Abstract A new and facile method to prepare large‐area silver‐coated silicon nanowire arrays for surface‐enhanced Raman spectroscopy (SERS)‐based sensing is introduced. High‐quality are prepared by a chemical etching used as template the generation of SERS‐active arrays. The morphologies type silver‐plating solution two key factors determining magnitude SERS signal enhancement sensitivity detection; they investigated in detail purpose optimization. optimized exhibit great potential...
3D network-like, hierarchically structured, porous nanowall NiO arrays were grown in situ on ceramic tubes by a facile but environmentally friendly hydrothermal reaction with subsequent calcination process. The constructed of the interconnected nanosheets, which further assembled abundant nanoparticles. gas-sensing properties such array film sensors investigated eight inorganic and organic gases. H2S-sensing performance was observed to be large dynamic range (1 ppb 100 ppm) lowest detection...
Monodisperse, hierarchical α-MoO3 hollow spheres were fabricated using a facile template-free solvothermal method combined with subsequent calcination. Various quantities of Au nanoparticles (NPs) deposited on the to construct hybrid nanomaterials for chemical gas sensors and their BTX sensing properties investigated. The 2.04 wt % Au-loaded sensor can detect effectively at 250 °C, especially, its responses 100 ppm toluene xylene are 17.5 22.1, respectively, which 4.6 3.9 times higher than...
Achieving reliable detection of trace levels NO2 gas is essential for environmental monitoring and protection human health protection. Herein, a thin-film sensor based on branched WO3/W18O49 heterostructures was fabricated. The optimized exhibited outstanding sensing properties with an ultrahigh response value (1038) low limit (10 ppb) at 50 °C. Such excellent performance could be ascribed to the synergistic effect accelerated charge transfer increased active sites, which confirmed by...
A facile and efficient strategy is described for the fabrication of soluble reduced graphene oxide (rGO) sheets. Different from conventional strategies, proposed method based on reduction by an endogenous reducing agent a most widely used cost-effective solvent, without adding any other toxic agent. Simultaneously, this solvent can serve as effective stabilizer, avoiding complicated time-consuming modification procedures. The as-prepared rGO sheets not only exhibit high level conductivity,...
Monodisperse vanadium pentoxide hollow spheres (VOHSs) were synthesized via a simple template-free solvothermal route followed by calcination in air. The as-prepared precursor and VOHSs characterized X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission (TEM), high-resolution (HRTEM) photoelectron (XPS). Diameters of these are the range 500–550 nm with shell thickness 55 nm. Building blocks nanoplates widths 50–80 lengths...
Two-dimensional ultrathin porous α-MoO3 nanosheets with oxygen vacancies were synthesized by a simple solvothermal method. The thickness of the precursor reaches 14 nm and is accumulated sheets 2–6 nm. pore size 2–10 on surface. A gas sensor was assembled annealed at 400 °C (α-MoO3-400). based α-MoO3-400 achieves fastest response to trimethylamine (TMA) relatively low operating temperature (133 °C). 198–50 ppm TMA detection limit 20 ppb. In addition, sensing mechanism verified experiment...

Most reported trimethylamine (TMA) sensors have to operate at high temperature, which will consume energy highly. To detect TMA low it is necessary modify the existing materials or develop new materials. In this paper, sensor based on MoO3/Bi2Mo3O12 hollow microspheres can work operating temperature of 170 °C, were prepared via a simple solvothermal route. The phase and morphology product characterized by an X-ray diffraction meter, scanning electron microscope transmission microscope....
Abstract Gas sensors based on metal oxides have attracted wide attention, due to their inherent advantages such as low cost, small size, fast response, and easy usage. Recently, much effort been put into the design of oxide‐based sensing materials further improve performance gas sensors. Among them, fabrication hierarchical has become most attractive strategy. In this article, authors widely review last decade development sensors, in which several representative gases including formaldehyde,...
