Rutile - A superior support for highly selective and stable Pd-based catalysts in the gas-phase acetoxylation of toluene

► 100% selectivity and higher catalyst stability ever was achieved with rutile-supported Pd,Sb particles. ► Uniform particles of optimum Pd/Sb ratio and surface valence on rutile stay active and coke-resistant. ► Beneficial effect of rutile related to weak or missing SMSI effect.
