Adsorptions of C5F10O decomposed compounds on the Cu-decorated NiS2 monolayer: a first-principles theory

Hailong Wu et al.

Summary: This study investigates the properties of Cu-decorated NiS2 monolayer and its adsorption and sensing performance for C5F10O decomposed species. The Cu atom is found to prefer the H1 site with a formation energy of -3.09 eV. Chemisorption occurs in the Cu-NiS2/C2F6O3 system, while physisorption occurs in the C3F6, CF2O, C2F6, and CF4 systems. The Cu-NiS2 monolayer shows potential as a reusable C3F6 or CF2O sensor and a high-sensitive one-shot C2F6O3 sensor, but is not suitable for C2F6 and CF4 sensing. This work is significant for proposing novel sensing materials for C5F10O-based insulation devices in the power system.

Optical hydrogen sensing by MoO3 films deposited by a facile flame synthesis method

M. A. Hosseini et al.

Summary: Nanostructured MoO3 films were deposited on glass at different substrate temperatures using an atmospheric solid-fed flame vapor deposition technique. The films exhibited different morphologies and structures depending on the temperature. The MoO3 films turned dark blue after hydrogen exposure, showing localized surface plasmon resonance absorption bands. The films demonstrated significant sensitivity to low concentrations of hydrogen and different working temperatures, with desirable repeatability and selectivity among interfering gases. Sample S300 at a working temperature of 150 degrees C showed the best sensing performance.

Hydrothermally grown α-MoO3 microfibers for photocatalytic degradation of methylene blue dye

Khemchand Dewangan et al.

Summary: This study reported the adsorption and photodegradation efficiency of alpha-MoO3 microfibers towards methylene blue dye. High-quality alpha-MoO3 microfibers were obtained through a hydrothermal treatment method, and the growth mechanism of the microfibers was explained. The experimental results demonstrated that alpha-MoO3 microfibers exhibited excellent photocatalytic properties for the degradation and removal of organic pollutants in water.

Nanocasting synthesis and highly-improved toluene gas-sensing performance of Co(3)O(4 )nanowires with high-valence Sn-doping

L. Wang et al.

Summary: Co3O4 nanowires arrays doped with different valence metal cations (Zn, In, and Sn) were successfully synthesized by nanocasting method. The cations doping had minimal effect on the morphology and mesoporous structures, but greatly influenced the gas-sensing performance, with higher valence metal cations leading to increased response. Additionally, Sn-doping was found to further improve the gas-sensing performance by enhancing the resistance in toluene gas.

The effect of doping MoSe2 by clusters of noble metals on its adsorption for NH3

Ahmad I. Ayesh

Summary: This study investigates the effect of noble metal doping of MoSe2 on its adsorption of NH3 gas. It is found that the doped MoSe2 structures exhibit significant changes in electronic characteristics and greatly enhanced adsorption capacity compared to the pristine structure. The study suggests that noble metal doping of MoSe2 can be a useful approach for developing sensitive NH3 gas detectors.

First principles study of Rh-doped SnO2 for highly sensitive and selective hydrogen detection

Qinkai Feng et al.

Summary: In this study, the adsorption and diffusion properties of different gases on Rh-doped SnO2 were investigated using first principles and molecular dynamics methods. It was found that Rh-SnO2 exhibits strong sensing characteristics towards H-2, while CH4, CO2 and N(2) only show weak physical adsorption. Additionally, the diffusion of H-2 in Rh-SnO2 is easier than that of other gases.

The interaction of two-dimensional P2SiS nanosheet with environmental toxic NCG molecules for sensor application: A DFT study

Vipin Kumar et al.

Summary: Gas sensors are crucial for detecting gas molecules on two-dimensional materials. The study investigated the sensing properties of NCG molecules on a 2D P2SiS nanosheet, revealing different adsorption behaviors and recovery times for NH3, NO, and NO2 gases. The findings suggest that the 2D P2SiS nanosheet can be a highly sensitive and reusable gas sensor material for NH3 and NO gases, but a disposable sensor material for NO2 gas.
