“…Furthermore, a comparison of the acetone sensing ability between the S3 sensor made in this work and SMOs-based sensors reported in previous literatures was summarized in Table . From the table, it was obvious that the 3D-IO PdO@In 2 O 3 MSs (S3 sensor) showed relatively faster response speed and lower optimal operating temperature. ,− …”

The design of semiconductor metal oxides (SMOs) with well-ordered porous structure has attracted tremendous attention owing to their larger specific surface area. Herein, three-dimensional inverse opal InO microspheres (3D-IO InO MSs) were fabricated through one-step ultrasonic spray pyrolysis (USP) which employed self-assembly sulfonated polystyrene (S-PS) spheres as a sacrificial template. The spherical pores observed in the 3D-IO InO MSs had diameters of about 4 and 80 nm. Subsequently, the catalytic palladium oxide nanoparticles (PdO NPs) were loaded on 3D-IO InO MSs via a simple impregnation method, and their gas sensing properties were investigated. In a comparison with pristine 3D-IO InO MSs, the 3D-IO PdO@InO MSs exhibited a 3.9 times higher response (R/R = 50.9) to 100 ppm acetone at 250 °C and a good acetone selectivity. The detection limit for acetone could extend down to ppb level. Furthermore, the 3D-IO PdO@InO MSs-based sensor also possess good long-term stability. The extraordinary sensing performance can be attributed to the novel 3D periodic porous structure, highly three-dimensional interconnection, larger specific surface area, size-tunable (meso- and macroscale) bimodal pores, and PdO NP catalysts.

“…To better evaluate the gas sensitivity features, the obtained results in this work were compared with those of other MOSs-based gas sensing materials (Table 1). Compared to previous sensors [13,14,20,32,[37][38][39][40], the synthesized ZnSnO 3 /α-Fe 2 O 3 composites displayed higher sensibilities towards acetone and lower optimal working temperatures. In this sense, the excellent gas sensing properties of ZnSnO 3 /α-Fe 2 O 3 composites can provide potential help for the diagnosis of diabetes.…”

“…For instance, ZnSnO 3 hollow microspheres were prepared by simple in situ precipitation method and exhibited a high sensitivity of 5.5 to 50 ppm acetone at 280 °C [13]. The ZnSnO 3 hollow polyhedrons with open nanoholes were synthesized via facile hydrothermal method and displayed the slow response-recovery speed (17/10 s) [14]. Uniform and monodisperse porous ZnSnO 3 cubes were synthesized by a aqueous solution method and showed the high response (37) to formaldehyde, but possessed poor selectivities [15].…”

Acetone, as one of the volatile organic compounds, is harmful to human health. Thus, fast detection at an early stage plays a vital role. ZnSnO 3 shows the merit for a wide range responsivity to VOCs, but the pure ZnSnO 3 has slow response-recovery speeds. Herein, the sensors based on urchin-like ZnSnO 3 /α-Fe 2 O 3 hierarchical hollow microspheres were synthesized by a simple two-step liquid-phase reaction. Porous α-Fe 2 O 3 nanowires with lengths of about 30 nm and diameters of around 2.5 nm were densely anchored on the surface of ZnSnO 3 microspheres, forming "urchin-like" geometries, which increased the specific surface area and supplied more active sites for the fast adsorption-desorption of gas molecules. An excellent gas sensing response value (14.24) and ultra-fast response-recovery times (3/8 s) have been recorded in as-obtained urchin-like ZnSnO 3 /α-Fe 2 O 3 composite sensors at 200 °C. Compared with the pure ZnSnO 3 and α-Fe 2 O 3 sensors, the ZnSnO 3 /α-Fe 2 O 3 sensor displayed an obvious enhancement in gas sensing properties for acetone, which can be put down to high surface area, porous nanostructure, and the synergistic effect of ZnSnO 3 and α-Fe 2 O 3 .

Carbon nanotubes (CNTs) have attracted many researcher’s attention in gas sensing field because of their excellent physical and chemical properties. Herein, Multi-walled carbon nanotubes (MWCNTs)/ZnSnO3 heterostructures have been obtained by a simple hydrothermal method without additional annealing process. The structural and composition information are characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The acetone sensing properties of pure MWCNTs, ZnSnO3 and MWCNTs/ZnSnO3 heterostructures are systematically investigated, respectively. The results show that MWCNTs/ZnSnO3 heterostructures have better sensing properties compared with pure MWCNTs and ZnSnO3 sample. Specifically, MWCNTs/ZnSnO3 heterostructures exhibit not only high responses of 24.1 and rapid response/recovery speed of 1 s/9 s to 100 ppm acetone, but also relatively good repeatability and long-term stability. The enhanced sensing performance is analyzed in detail. In addition, this work provides the experimental and theory basis for synthesis of high-performance MWCNT-based chemical sensors.
