密度泛函理论研究Pu+O2反应机理及键的特点
Density function theoretical study on the Pu+O2 reaction mechanism
摘要
Abstract
The theory model of the interaction between Pu atom and O2 was built and a systematic density functional theory computational study is reported here.The structures of reactants, transition states, intermediates and final products are optimized.All the transition states are verified by the vibration analysis and intrinsic reaction coordinate calculations.The nature of the bonding evolution along the reaction pathways was explored using distinct analysis method including electron localization function(ELF), atoms-in-molecules(AIM).The results indicate that the final reaction products of O-O breakage are the PuO2 and PuO+O.In addition, the reaction of Pu+O2→PuO2 is more energy supported.关键词
