TL;DR: It is reported here that supported gold-palladium nanoparticles on carbon or TiO2 are active for the oxidation of the primary carbon-hydrogen bonds in toluene and related molecules, giving high selectivities to benzyl benzoate under mild solvent-free conditions.

TL;DR: A procedure to effectively remove the ligands without affecting particle morphology is reported, which enhances the surface exposure of the nanoparticles and their catalytic activity over a range of reactions.

TL;DR: It is demonstrated that this particular elemental segregation provides optimal positioning of the unoccupied d-orbital states, which results in an enhanced utilization of the photoexcited electrons in redox reactions, and it is considered that the enhanced activity observed on TiO2 is generic in nature and can be transferred to other narrow band gap semiconductor supports for visible light photocatalysis.

TL;DR: The results suggest that the metal nanoparticles not only play a role in capturing photogenerated electrons, but are strongly involved in the photocatalytic reaction mechanism, and Interestingly, the as-prepared Pd and Au-Pd decorated TiO(2) materials exhibit excellent long-term photoactivity.

TL;DR: The preparation of Au-Pd nanocrystalline catalysts supported on activated carbon prepared via a sol-immobilization technique is reported and their use for the direct synthesis of hydrogen peroxide and the oxidation of benzyl alcohol is explored.
