The SMSI between the active species of Ni and rare earth oxides depresses the growth and the migration of Ni, as well a...
在实验中还发现CeO2容易进行Ce3＋Ce4＋氧化还原反应而对反应具有催化活性。
The strong metal-support interaction is employed to explain the decrease activity of the HTR pretreated catalyst in comparison with the LTR pretreated Pd/TiO〓 and Pd/CeO〓. The similarity of catalytic performance for LTR and HTR pretreated Pd/Ce20Ti is confirmed by the absence of SMSI effect.
CO吸附红外漫反射谱显示各催化剂中CO-Pd的吸附性不同，反映了金属载体电子效应不同；而CO-TPR显示PdO不同的还原性，源于其在载体上的位置或取向附生方向的不同，反映了几何因素对金属-载体相互作用的影响。
Catalytic Performance and the SMSI Effect of Palladium-Only Catalyst with Optimized Size of Supports
优化载体粒径单钯催化剂性能及组分间相互作用研究
TiO_2 support is a newfashioned catalyst carrier in recent years. TiO_2 support became the studying focus since researchers of Exxon Company found the SMSI on titanic supported noble metal catalyst in 1978. Preparation and performances of TiO_2 support were studied in this thesis.
二氧化钛载体是近年来才发展起来的一种新型的催化剂载体，而二氧化钛催化剂载体成为研究热点是从1978年Exxon公司的研究人员发现了二氧化钛载体与贵金属的强相互作用开始的。
The theoretical analysis and experimental result of self mixing laser speckle interference (SMSI) velocimeter for flow measurement are presented based on the theory of Fabry P é rot (F P) cavity model.
提出了一种简便的激光自混合散斑干涉测量流体速度的方法。根据散斑和法布里珀罗腔的理论，提出了半导体激光器的自混合散斑干涉模型。
