Heterogeneous macroporous supports

Surface-modification of meso- and macroporous supports, surface immobilization of oi anometallic catalysts, application in heterogeneous catalysis... 

X 102 nm. This is the range of meso/macropores. Unfortunately, the quite small size of these bubbles (fitting well with the dp value of the most common catalyst supports) are produced at uncommonly high frequencies (15 MHz at 1 atm). Therefore it seems reasonable to consider that the most important sonochemical effect in heterogeneous catalysis occurs mainly inside the large macropores (dp 50 nm) at frequencies on the order of kHz.
