摘要

油浸式变压器中的微量水分严重影响着变压器的油纸绝缘性能，实现变压器中微量水分的在线监测至关重要。文中以水分子（H

O）在NiO掺杂MoTe

单层上的吸附结构、吸附能（

）、电荷转移量（Δ

）、态密度（DOS）、最高占据及最低未占据分子轨道（HOMO-LUMO）、功函数（

）和差分电荷密度（DCD）为计算对象，基于泛函密度函数理论（density function theory，DFT）计算研究了过渡金属氧化物（NiO）掺杂对单层MoTe

吸附参数和电子性质的影响。结果表明：与本征单层MoTe

相比，过渡金属氧化物（NiO）掺杂单层MoTe

的化学活性明显增强。此外，NiO掺杂的单层MoTe

对H

O分子均表现出优异的吸附及解吸附能力。因此，基于NiO掺杂的单层MoTe

气敏材料可进一步用于在油浸式变压器微量水分的在线监测领域。

Abstract

The trace moisture in oil-immersed transformers seriously affects the oil-paper insulation performance of transformers. It is important to realize online monitoring of the trace moisture in transformers. In this paper

the adsorption structure

adsorption energy (

)

charge transfer (Δ

)

density of states (DOS)

the highest occupied and lowest unoccupied molecular orbital (HOMO-LUMO)

work function (

) and differential charge densi

ty (DCD) of water molecules (H

O) on NiO doped MoTe

monolayers are taken as the calculation object. Based on density function theory (DFT) calculation

the effects of transition metal oxide (NiO) doping on the adsorbed parameters and electronic properties of MoTe

monolayer are studied for the adsorption mechanism. The result shows that the chemical activity of transition metal oxides (NiO) doped MoTe

monolayer is significantly enhanced compared with the pristine MoTe

monolayer. In addition

NiO doped MoTe

monolayer shows excellent adsorption and desorption ability for H

O molecules. Therefore

the NiO dopped MoTe

monolayer gas sensing materials can be further applied in the field of online monitoring of trace moisture in oil-immersed transformers.
