Abstract
Measurements of beta-PdHx stoichiometry by hydrogen TPD and of Pd disp ersion by CO chemisorption has shown that in Pd-SiO2 catalysts the for mation of beta-PDHx is more and more hindered,vith the increase of Pd dispersion in the whole dispersion range. A linear relationship exists between beta-PdHx stoichiometry and temperature of its hydrogen TPD p eak.
