Resumen:
bstract: 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 they can
absorb or deliver, but rather because of the reducing free radicals they can generate. Efficient
photochemical nanoparticle generation thus requires a careful selection of substrates and
experimental conditions such that free radical generation occurs with high quantum efficiency,
where metal ion precursors do not inhibit radical formation. A key consideration to
achieve nanoparticle synthesis with short exposure times is to minimize excited-state quenching
by metal ions.
Applications of nanostructures in catalysis require control of the nanoparticle characteristics,
such as dimension, morphology, and surface properties. Part of this article describes
the strategies to modify photochemically prepared particles. Fi
