Gold nanoparticles (AuNP) supported on hydrotalcite, γ-Al2O3 and TiO2 P25 have been prepared photochemically under mild conditions using ketyl radicals as the primary reducing agent; these nanocomposites were prepared directly in the solid phase. Su

The ketone-photoinduced formation of Au, Ag, and Cu nanoparticles from their corresponding ions in solution has been carried out using benzoin photoinitiators. Ketones are good photosensitizers for nanoparticle synthesis not because of the energy the

The photochemistry of aromatic ketones through the Norrish type I cleavage of benzoins and via photoreduction generates ketyl radicals that readily reduce many metal ions, including silver and gold. Reduction to Au(0) and Ag(0) leads to the spontaneo

A comprehensive study of the ketone-photoinduced formation of gold nanoparticles (AuNPs) from gold ions in aqueous and micellar solution has been carried out. Ketones are good photosensitizers for nanoparticle synthesis not because of the energy they

Gold nanoparticles (AuNP) can be used as seeds for the synthesis of larger AuNP of controllable size with narrow size distribution by photochemical reduction of additional Au(III) using water-soluble benzoins or H(2)O(2) as sources of reducing radica

Photochemical methods for free radical generation can provide a powerful tool to design new strategies for the synthesis of metal nanostructures. In particular, the Norrish type I cleavage of substituted benzoins can be employed as a source of strong

The photolysis of gold salts is rarely viewed as the initiation for gold nanoparticle (AuNP) formation. Yet, photolysis of AuCl(4)(-) generates chlorine atoms whose rich hydrogen transfer chemistry can readily generate strongly reducing radicals. Int

The photodecomposition of ketones by the Norrish Type I reaction, leading to the efficient release of reducing ketyl or alpha-amino alkyl radicals, provides a facile route for the synthesis of copper nanoparticles (CuNP) in both aqueous and organic s
