Involvement of Surface‐Bound Radicals in the Oxidation of Toluene Using Supported Au‐Pd Nanoparticles

Au-Pd nanoparticles having a mean particle size of 3–4 nm and supported on titania (see figure; scale bar 2 nm) exhibit high activity in the selective oxidation of aromatic hydrocarbons using tert-butyl hydroperoxide as an oxidant. The supported nanoparticles stabilize surface-bound radicals.
