过渡金属团簇M_2^+(M=Fe、CO、Ni)与CO的化学反应

Chemical Reactions of Transition-metals with CO

利用离子讲质谱计和激光溅射技术相结合，研究了Fe2＋、CO2＋、Ni2＋与CO气体的吸附反应，比较了它们的反应活性，给出了化学反应的速率常数及随反应气体压强的变化关系，并从理论上模拟了化学反应过程，测量结果与已有的实验值符合较好．

Chemical reactions of cluster ions of transition-metals (Fe2+ Co2+ Ni2+) with CO were studied by using an ion trap affixed with a laser ablation source.The experiments mdicate that Co2+ is more reactive than Fe2+ and Ni2+ when they react with CO molecule,and the reaction rates are indepenent on CO pressure. The results are in agreement with the theoretical simulation and the previous data.
