Vi. Savchenko et Ka. Dadayan, ON THE POSSIBLE ROLE OF ADPARTICLES SPILLOVER ON A HETEROPHASE SURFACE IN CAUSING SUPERADDITIVE ACTIVITY, Reaction kinetics and catalysis letters, 55(1), 1995, pp. 33-40
It is shown that for a two-stage reaction on the surface involving two
types of surface patches with adsorption heats lower and higher than
q(opt), migration of adparticles between surface patches (spillover) c
an both increase and decrease the reaction rate.
