Abstract ：
Monoclinic BiVO4 material was successfully synthesized through a hydrothermal method, and silver (Ag) nanoparticles were deposited onto the surface of BiVO4 using the photo deposition technique. The gas-sensing outcomes demonstrate that the BiVO4 material loaded with 2 wt% Ag has a good gas-sensing response to isopropanol, which is about three times that of pure BiVO4. In addition, it exhibits a fast response within 10 s and well-stability. The improved gas sensing properties primarily come from the catalytic and spillover effect mechanism of Ag.

Abstract ：
Two-dimensional (2D) perovskite PbTiO3 is an important ferroelectric material with spontaneous polarization below Curie temperature and readily adsorbs oxygen molecules in the atmosphere, a preliminary step for NH3 response. However, the surface of 2D PbTiO3 lacks enough active adsorption sites for NH3 gas. Here, 2D PbTiO3 nanoplates (NLs) with highly polarized (001) plane was synthesized by a two-step hydrothermal strategy without templates and surfactants, and Ag+ ions on (001) plane were further in-situ reduced by an impregnation method. Specially, the negatively polarized surface (zeta (zeta potential) =-22.3 mV) for (001) plane promoted the reduction of Ag+ ions in AgNO3 solution to Ag0 nanoparticles (NPs). Where, Ag NPs with high density on (001) plane can produce spillover effect, promoting adsorption of O2 in air and subsequent formation of O2-. The response of PbTiO3-based gas sensor to 100 ppm NH3 is 3.6 at room temperature (25 degrees C), while the response is improved by 2.6 times on 1.5 at% Ag/PbTiO3 NLs with Schottky junctions. Even at 15 degrees C, the response reaches to 6. The ammonia sensor based on Ag/PbTiO3 NFs is verified with high sensitivity, fast response-recovery and distinct selectivity at low operating temperature.

Abstract ：
The sea urchin-like In2O3 material was successfully synthesized through a simple hydrothermal method. Furthermore, the material underwent surface decoration without adding extra indium ions, resulting in the formation of a thin MIL-68(In) layer on the surface of In2O3. The obtained In2O3@MIL-68(In) retains the sea urchin-like morphology while acquiring an additional porous structure. Compared to pure In2O3, the composite exhibits a significant increase in specific surface area, leading to enhanced gas sensitivity. Notably, it demonstrates exceptional sensitivity towards formaldehyde gas, with a response of 18 at 100 ppm at 300 degrees C, up to six times more than pure In2O3. Moreover, In2O3@MIL-68(In) showcases remarkable selectivity and stability. These findings suggest that surface-modified MOF can enhance gas-sensitive properties.

Abstract ：
Shape controlled preparation and doping are important means to improve the gas sensitivity of metal oxide semiconductor materials. In this work, pure and Co-doped In2O3 porous hollow hexagonal cylinders were suc-cessfully prepared using metal-organic frameworks (MOFs) MIL-68(In) as self-sacrificial template. The size of the MIL-68(In) hexagonal cylinder is uniform, and the In2O3 obtained after pyrolysis better inherits the shape of the MIL-68(In), but becomes hollow, and the cylinder surfaces are porous. The product has a large specific surface area (46.52 m(2)/g), and the doping of Co significantly increases the oxygen vacancy of the material. The Co-doped sample obtained by pyrolysis at 500 degrees C has excellent gas sensing performances to ethanol gas, its sensitivity to 100 ppm ethanol gas at 210 degrees C is 14.6, response/recovery time is 21 s and 107 s, and the sensing selectivity to ethanol is also good.

A novel spindle hierarchical ZnO was grown on ITO glass substrate via a solvothermal process and subsequent calcination treatment. The core of the hierarchical structure is a bundle of nanorods, and the bundle is wrapped by a nano-ring and put on a "sarong" formed by nanoparticles. This ZnO hierarchical structure has good photocatalytic activity and gas sensitivity, its degradation rate to rhodamine B is twice that of ordinary ZnO powder, and response sensitivity to 100 ppm acetone gas is as high as 48.1, which is 11 times as that of ordinary ZnO powder.

Abstract ：
In this work, a distinctive hierarchical tree-like rutile TiO2 architecture growing directly on the conductive surface of indium tin oxide (ITO) conductive glass substrates was successfully prepared via a facile one-step hydrothermal process, where titanium butoxide used as Ti source and HCl as an acidic medium solution. The as-obtained products were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED) and applied in gas sensor. The characterization of FE-SEM indicates that the morphology of the products can be controlled by regulating solution acidity, the amount of titanium butoxide, reaction time, addition agents, and so on. The gas sensing test shows that the sensor fabricated with 3D nanotree-like rutile TiO2 has higher gas response towards CH3COCH3 gas than those with 1D rod-like TiO2 or common TiO2 precipitate, indicating that the 3D nanotree-like architectures may be promising gas sensitive materials.
