Abstract
Employing modern fabrication technologies, one can prepare catalysts consis ting of nm metal crystallites deposited on mum oxide particles located on a planar oxide or metal support. We derive general equations for estimation of the time scales characterizing dissipation of heat released in exothermi c reactions occurring on such catalysts. Using the results obtained, we sho w that in such systems overheating of oxide particles is usually negligible .
