Surface reorganization of carbon supported cobalt catalysts during CO chemisorption

  • A. Guerrero-Ruiz

Different monometallic catalysts containing Fe, Co or Ni and a Fe−Co bimetallic catalyst have been prepared by impregnation of an activated carbon. The formation of subcarbonyl species during CO adsorption, as detected by the slow adsorption rate, was observed. From the CO adsorption isotherms, the possibility of a surface reorganization in the Co catalysts induced by the interaction with CO is deduced.

Различные монометаллические катализаторы, содержащие Fe, Co или Ni и биметаллический катализатор Fe−Co были приготовлены импрегнированием активированного углерода. Образование субкарбонильных частиц в ходе адсорбции CO было детектировано с помощью медленной скорости адсорбции. Из изотерм адсорбции Co заключали о возможности реорганизации поверхности кобальтовых катализаторов, индуцированной взаимодействием с CO.
