钨镍双金属有机框架敏化的辐射甲烷氧化研究
Radiation-induced methane oxidation promoted by tungsten nickel bimetallic organic framework
摘要
Abstract
Methane oxidation is a crucial chemical process,yet it encounters challenges like high energy consumption and multiple steps.This study initially demonstrated the feasibility of oxidizing methane into methanol and formaldehyde liquid proliferation products using water radiolysis radicals(•OH,•OOH,O2•-).To further enhance energy efficiency and product selectivity,this paper synthesized a W,Ni bimetallic organic framework material(WNi-UMOF)featuring a two-dimensional ultrathin nanosheet structure.Electron spin resonance and in-situ infrared Fourier transform spectroscopy tests revealed that the unique structure and abundant metal active sites of WNi-UMOF contribute to enhancing the yield of radicals and guiding the directional conversion of reactive intermediates.Radiation synthesis performance studies indicated that under ambient temperature and pressure,the selectivity of methanol product from WNi-UMOF radiation synthesis was increased to a maximum of 81.6％.关键词
