RODRIGUEZ, A et al. Estudio de las especies de oxígeno adsorbido sobre catalizadores de NiO/MgO-La2O3, a través de la técnica de Kelvin. Rev. mex. fis. [online]. 2006, vol.52, suppl.3, pp.211-213. ISSN 0035-001X.

In this work we present the results of the oxygen adsorption on the NiO/MgO-La2O3 catalysts studied by the Kelvin probe technique. We have found that oxygen was adsorbed, for temperatures less than 423 K, as O- species over all the solid, while for the temperature range between 623 and 698 K was adsorbed as the O= species on 100La-20Ni, and as O- 2 species on 100Ma-20Ni.

Keywords : Kelvin; catalysts; oxygen.
