【摘要】 本文通过制备具有表面拉曼增强活性的金属Rh基底 ,将表面拉曼光谱技术拓展到固 液和固 气体系的吸附和反应研究。同时也初步了解了上述两种环境下Rh表面氧化物的还原情况。结果表明 ,无论是在固 液还是固 气体系 ,激光在还原过程中起着重要的作用。通过两个体系所得结果的比较 ,可以看到这两种体系中金属Rh表面氧化物还原行为的相似和不同更多还原

【Abstract】 Surface Raman spectroscopy has been successfully extended to the studs of adsorption and reaction in solid/liquid and solid/gas interfaces, by preparing rhodium substrates of surface-enhanced Raman activity The reduction process of rhodium oxides has also been investigated It was shown that, the laser plays an important role during the reduction process at both interfaces The comparison between the results reveals the similarities and differences of the reduction behavior of rhodium oxides更多还原
