DFT Study of Metal (Ag, Au, Pt)-Modified SnS₂ for Adsorption of SF₆ Decomposition Gases in Gas-Insulated Switchgear

Langmuir, Journal Year: 2024, Volume and Issue: 40(13), P. 7049 - 7059

Published: March 23, 2024

In this study, the gas-sensitive response of metal (Ag, Au, Pt)-modified SnS2 toward SF6 decomposition gases (SOF2, SO2F2, SO2, H2S) in gas-insulated switchgear was studied by analyzing adsorption structure, band charge transfer, and density states based on functional theory. The results show that four target pristine belongs to weak physical adsorption. Compared with SnS2, energy transition atom-modified monolayer has been improved a certain extent capacity these obviously improved. Moreover, recovery time Ag-SnS2/SOF2, Ag-SnS2/SO2F2, Au-SnS2/SOF2, Au-SnS2/SO2F2, Pt-SnS2/SO2F2 is too short, indicating conditions have poor sensitivity are not suitable as detection materials for gases. According different changes conductivity during adsorption, it provides feasible solution detect each gas. This theoretical study effectively explained sensing properties between metal-modified monolayers

Gas-Sensitive Performance Study of Metal (Au, Pd, Pt)/ZnO Heterojunction Gas Sensors for Dissolved Gases in Transformer Oil

Langmuir, Journal Year: 2024, Volume and Issue: 40(18), P. 9819 - 9830

Published: April 25, 2024

An oil-immersed transformer is a critical electrical device for power delivery. Online monitoring of operation the key to ensuring regular systems. This paper proposes Au/ZnO, Pd/ZnO, and Pt/ZnO heterojunctions as new gas-sensitive materials investigates their performance dissolved gases (C2H4, CO, H2) in oil. Upon theoretical density functional theory (DFT) calculations, analysis total states (TDOS), partial (PDOS), molecular orbital theory, charge deformation reveals that Au, Pd, Pt form with ZnO, which enhance conductivity system. Meanwhile, intrinsic ZnO unsuitable gas detection adsorption, while Au/ZnO heterojunction suits C2H4 detection. In contrast, Pd/ZnO suitable H2 detection, CO The adsorption models changed varying degrees after adsorption. different change rate just serves foundation determining type concentration research results act constructing sensors ZnO-based material.

Substrate Engineering toward Selective Growth of Ultrathin WC Crystals and Heterostructures via Liquid Cu‐Zn Catalyst

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: 34(32)

Published: March 29, 2024

Abstract Transition metal carbides (TMCs) grown by chemical vapor deposition (CVD) offer promise for numerous novel phenomena and applications in the 2D limit. Despite considerable efforts thus far, flexible customization of TMCs their heterostructures still remains challenging. Herein, a substrate engineering is developed to achieve customized manufacturing ultrathin WC single crystals WC/graphene (WC‐G) varying concentration Zn Cu‐Zn alloy substrate. It worth noting that atoms can remarkably reduce nucleation density graphene promote WC. Thus, an increasing content applied synergistically modulate growth WC, enabling controllable fabrication WC‐G heterostructures. The synthesized exhibit nature down 3 nm, as well high crystalline, ultra‐clean surface, superb stability. Based on that, typical metallic properties with temperature‐dependent resistance (nearly 1.30 Ω at 300 K nearly 0.08 1.7 K) low excellent nonlinear optical performance are demonstrated. This work provides fresh insights into regulating behavior multiblock‐structured promotes study optic electronic properties.
