A great show at the Palladium : Precipitation of Mo–V–Nb oxides in the presence of colloidal TiO 2 leads to more dispersed active structures and much higher rates of ethene oxidation to acetic acid. The presence of trace amounts of palladium as supported clusters in physical mixtures (<0.05 % w/w) catalyzes the formation of acetaldehyde intermediates and leads to unprecedented rates and selectivities in the synthesis of acetic acid from ethene and O 2 .
