Photochemistry of Methane on Pd/Al(2)O(3) Model Catalysts: Control of Photochemistry on Transition Metal Surfaces.
The mean size of the Pd clusters deposited on an Al(2)O(3) thin film influences the efficiency of photodissociation of CD(4) into CD(3) and D as well as the photodesorpion upon irradiation with 193-nm laser light. The picture shows the degree of desorption on Pd clusters of various sizes (as well as on a Pd(111) single-crystal surface) as a function of temperature; the values given refer to the average thickness of the evaporated metal layer.
