Using first-principles theory, we investigated the most stable configuration for Rh dopant on a MoSe2 monolayer, and interaction of Rh-doped (Rh-MoSe2) monolayer with four toxic gases (CO, NO, NO2 SO2) to exploit potential application Rh-MoS2 as gas sensor or adsorbent. Based adsorption behavior comparison other 2D adsorbents desorption analysis, assume that Rh-MoSe2 is desirable adsorbent CO, NO storage removal given larger energy (Ead) -2.00, -2.56 -1.88 eV, respectively, compared...
A gas sensor is used to detect SF6 decomposed gases, which are related insulation faults, accurately assess the insulated status of electrical equipment. Graphene films (GrF) modified with Au nanoparticles as an adsorbent for detection H2S and SOF2, two characteristic products gases. Sensing experiments conducted at room temperature. Results demonstrate that Au-modified GrF yields opposite responses tested gases thus considered a promising material developing H2S- SOF2-selective sensors. The...
Partial discharge (PD) is usually aroused before the failure of gas insulated switchgear (GIS) caused by defects, which results in decomposition SF <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6</sub> used as insulating gas. Analyzing products can aid PD detection. Before recognizing types analyzing SF6 products, characteristics under different should be investigated first. In this paper, a chamber and four typical artificial defects were...

Plasma-catalytic CO2 hydrogenation for methanol production is gaining increasing interest, but our understanding of its reaction mechanism remains primitive. We present a combined experimental/computational study on plasma-catalytic to CH3OH over size-selected Cu/γ-Al2O3 catalyst.
