Study on developments of highly efficient selective oxidation and fuel cell oxidation catalysts and real-time structure information

我们开发了一种用于动态催化研究的时间分辨x射线吸收精细结构（XAFS）技术。这种复杂的技术使我们能够研究催化剂在工作条件下的结构动力学/动力学。开发了苯直接合成苯酚和过量H2条件下CO优先氧化的新催化剂，并揭示了其活性结构。首次阐明了燃料电池Pt/C阴极催化剂在电压运行过程中的实时动力学。

We have developed a time-resolved x-ray absorption fine structure (XAFS) technique for dynamic catalysis research. This sophisticated technique allows us to investigate the structure kinetics/dynamics of catalysts under the working conditions. New catalysts for the direct phenol synthesis from benzene and the preferential CO oxidation under excess H2 were developed and their active structures were revealed. The real-time kinetics of a fuel cell Pt/C cathode catalyst in the voltage operation process was at first elucidated.
