| 摘 要： | 自然界中最廉价和最丰富的碳资源CO2的有效利用已成为全球普遍关注的重要课题之一1].自80年代起,基于回收工业废气中的CO2的可能性以及用CO2取代石油作为精细化学品合成的基本原料的重大意义,有关CO2活化的研究日趋活跃2].考察过渡金属与CO2的相互作用是研究过渡金属催化活化CO2的基础.加热蒸发从Ti到Cu的过渡金属与CO2作用,一般都能得到相应金属的CO2配合物3].

| Abstract: | nm pulsed laser\|ablated Ta atoms react with carbon dioxide to form products TaCO, OTaCO and O\-2Ta(CO)\-2, which have been isolated in argon matrices and identified by their FTIR spectra and a comparison of the spectra of O\-\%x\%W(CO)\-\%y\%. Annealing of matrix isolated sample results in the growth of OTaCO and O\-2Ta(CO)\-2, and further 266 nm laser irradiation leads to the increase of OTaCO as well as the formation of O\-2TaCO. |
