Catalytic oxidation of toluene over Pd loaded hierarchically porous group Vb systems, and the supports alone, has shown that supports synthesised at pH 6 are the most active, despite having lower specific surfaces, thus implying modifications to the surface chemistry in the presence of H+ or OH− can affect the overall performance of the supported catalytic system.Show less >
