- W1551736253 abstract "通过DFT-UB3LYP方法,计算了五重、三重和单重自旋态下的气相Nb^+离子活化甲烷脱氢反应的能量变化,并对其直接式和插入式反应机理进行了比较,考察了自旋翻转对反应的影响,结果表明,插入式脱氢较直接式有利,CH4上的H转移到Nb^+上形成的中间体HNbCH3+中,多重度由五重降为三重,反应活化能垒显著降低;HNbCH3+可经四中心过渡态转化为(H2)NbCH2^+,最后生成三重态的NbCH2^+H2.速控步骤为(H2)NbCH2^++的脱氢.此外,通过对V^+,Nb^+,Ta^+活化甲烷的比较研究了三者活化甲烷的反应活性." @default.
