Engineering Research Equipment Grant: Laser Raman Spectrometer

正在购买一台激光拉曼光谱仪。该仪器将提供进行多相催化研究的能力。这些能力无法与任何可用的设施相匹配。将激光拉曼光谱技术结合到正在进行的低分子量碳氢化合物的选择性氧化和有机空气污染物的催化焚烧研究项目中，将为催化剂合成过程的原位表征、反应条件下催化剂表面的表征等研究开辟新的途径。吸附剂-吸附物相互作用的研究，催化剂失活过程的原位表征以及使用同位素标记的反应物识别活性催化位点。由于催化剂表面的原位表征是深入了解催化现象的关键，因此该技术的可用性将有助于我们回答有关催化活性、选择性和反应方案的几个基本问题。只有这样的基本认识才能使活性和选择性催化剂的固态设计成为可能。

A laser Raman spectrometer is being acquired. This instrument will provide capabilities for conducting research in heterogeneous catalysis. These capabilities cannot be matched with any of the available facilities. Incorporation of the laser Raman spectroscopy technique to the ongoing research programs on selective oxidation of lower molecular weight hydrocarbons and on catalytic incineration of organic air pollutants will open up new avenues for research such as in situ characterization of the catalyst synthesis process, characterization of catalyst surfaces under reaction conditions, investigation of adsorbent-adsorbate interactions, in situ characterization of catalyst deactivation process and identification of active catalytic sites by use of isotopically labelled reactants. Since in situ characterization of catalyst surfaces is the key to acquiring an indepth understanding of the catalysis phenomenon, availability of this technique will help us answer several fundamental questions regarding catalytic activity, selectivity and reaction schemes. Only such fundamental understanding will make the solid state design of active and selective catalysts possible.
