Ge掺杂磷烯材料吸附气体分子的第一性原理研究
First Principles Study on the Adsorption of Gas Molecules on Ge Doped Phosphorene Materials
摘要
Abstract
Through first-principles calculations,we systematically investigate the adsorption performance of mole-cules such as NO2,NO,CO,CO2,CH4 and SO2 on Ge-doped phosphorene by optimizing geometric structures and analyzing corresponding electronic properties.The adsorption positions of these molecules on the material surface are identified,and the most stable adsorption configurations are determined.The study reveals that Ge-doped phosphorene exhibits strong ad-sorption capabilities toward molecules such as NO2,NO,CO,CO2,CH4 and SO2,indicating its potential application pros-pects in gas molecule adsorption.Furthermore,the influence of Ge doping on the electronic structure of the material is ex-plored.Results demonstrate that Ge doping introduces new energy levels,which modify the conductive properties of the ma-terial and consequently regulate the interactions between adsorbed molecules and the substrate.This provides a theoretical foundation for understanding the adsorption mechanisms of gas molecules on Ge-doped phosphorene.In summary,this work highlights the superior performance of Ge-doped phosphorene in adsorbing molecules such as NO2,NO,CO,CO2,CH4 and SO2,while offering theoretical insights into its potential applications in gas adsorption and related fields.These findings hold significant implications for developing novel high-efficiency adsorption materials to address environmental and energy challenges.关键词
