| Abstract: | It has been found that the stoichiometry of adsorption of oxygen on nickel supported on silica is linearly correlated to the particle size of the metal. It is shown that the combined use of hydrogen and oxygen chemisorption at room temperature allows to determine both the dispersity and reduction degree of nickel.
