Samples of vanadia on SBA-15 where the support surface roughness was systematically varied were tested in the catalytic partial oxidation of methanol. Results show that supports with rougher surfaces exhibit reduced catayst performance, due primarily to the ability of rough surfaces to stabilize less catalytically-active monomeric vanadia species.
