Abstract:

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 indicate that Co2+ is more reactive than Fe2+ and Ni2+ when they react with CO molecule, and the reaction rates are independent on CO pressure. The results are in agreement with the theoretical simulation and the previous data.
