摘  要:
基于第一性原理计算,详细研究了完美的金红石型Ti O2(110)面上CH3OH转化为HCOOCH3的氧化机制。计算所得的基元反应的能垒证实了CH3OH在Ti O2(110)表面上经过脱氢和耦合反应生成了中间物CH3OC(=O)H2,然后经过脱氢生成了最终的产物HCOOCH3。

摘  要:
The detailed oxidation of methanol into methyl format on the perfect and defect rutile Ti O2( 110)surfaces was explored based on first principles calculations. the calculated energy barriers of elementary steps demonstrated that CH3 OH was transferred into an intermediate hemiacetal via dehydrogenating and coupling reaction,and then produced the final product methyl format through the dehydrogenation.
