Resumen:
n recent years, the synthesis of metal nanoparticles has attracted
significant attention because of their unique properties. These
nanoparticles are useful for diverse fields including catalysis,
electronics, clinical diagnosis, etc. Although many strategies for the
preparation of noble- and transition-metal nanoparticles have been
published, the synthesis of indium nanoparticles (InNPs) has been
scarcely reported. Some top-down methods involve the use of specific
equipments and/or high temperatures, and most of the bottom-up methods
require the use of indium salts and strong reducing agents such as
sodium metal, zinc power, alkalides/electrides, or decomposition of
organometallic complexes.
Regrettably, some of them provide little control over particle size and
size distribution, and generally it is mandatory the presence of
stabilizing agents. On the other hand, the reducing systems based on the
use of alkali-metals in combination with arenes in aprotic media, with
the arene acting as electron carrier have received much attention. Some
of us have been working on the preparation of transition metal
nanoparticles by fast reduction of the corresponding metal chlorides
with lithium and a catalytic amount of an arene [naphthalene,
4,4´-di-tert-butylbiphenyl (DTBB)].
