Abstract

The diffusion-controlled reaction between a molecule (excited Ru(bpy)32+) adsorbed at the irregular surface of porous silicas and a reactant (anthracene) diffusing from an intrapore liquid phase was studied by nanosecond laser excitation. It was found that the reaction is controlled by the short-range irregularity of the surface but not by the average pore diameter (in the 40-1000-Å range). It is suggested that the chemical reactivity correlates with the fractal dimension of the surface accessible for adsorption.
