Hollow In2O3@TiO2 double-layer nanospheres were prepared via a facile water bath method using the sacrifice template of carbon nanospheres. It is shown that size In2O3/TiO2 nanocomposites 150-250 nm, thickness In2O3 shell about 10 and TiO2 15 nm. The sensing performances synthesized nanocomposites-based chemiresistive-type sensor to formaldehyde (HCHO) gas under UV light activation at room temperature have been studied. Compared pure In2O3- TiO2-based sensors, nanocomposite exhibits much better formaldehyde. response nanocomposite-based 1 ppm 3.8, time recovery are 28 50 s, respectively. detectable concentration can reach as low 0.06 ppm. role formed heterojunctions involved chemical reactions activated by investigated AC impedance spectroscopy in situ diffuse reflectance Fourier transform infrared spectroscopy. improvement properties could be attributed nanoheterojunctions between two components "combined photocatalytic effects" UV-light-emitting diode irradiation. Density functional theory calculations demonstrated introducing improve adsorption energy charge transfer materials.

Detection of hazardous toxic gases for air pollution monitoring and medical diagnosis has attracted the attention researchers in order to realize sufficiently sensitive gas sensors. In this paper, we fabricated characterized a Titanium dioxide (TiO2)-based sensor enhanced using gold nanoparticles. Thermal oxidation sputter deposition methods were used synthesize sensor. X-ray diffraction analysis was determine anatase structure TiO2samples. It found that presence nanoparticles on surface TiO2enhances sensitivity response sensors by up about 40%. The showed 1.1, 1.07 1.03 50 ppm acetone, methanol ethanol vapors at room temperature, respectively. Additionally, reduce s time (about 50% reduction) vapor; demonstrated recovery decorated TiO2sensor is less than 40 s. Moreover, explain improved performance depends adsorption-desorption mechanism, chemical sensitization electronic

In this work, MXene/NiO-composite-based formaldehyde (HCHO) sensing materials were successfully synthesized by an in situ precipitation method. The heterostructures between the MXene and NiO nanoparticles verified transmission electron microscopy (TEM), X-ray diffraction (XRD), photoelectron spectroscopy (XPS). HCHO performance of MXene/NiO-based chemiresistive-type sensors was investigated. Compared to pure materials, MXene/NiO-P2-based sensor gas at room temperature significantly enhanced formation MXene/NiO heterojunctions. response MXene/NiO-P2 50 ppm 8.8, which much higher than that NiO. At temperature, detectable concentration 1 ppm, recovery time 2 279 s 346 s, respectively. also exhibited a good selectivity long-term stability for 56 days. Fourier transform infrared (FTIR) spectra sensor, when exposed different times, investigated verify adsorption reaction products molecules.
