Porous nanomaterial catalyzed green synthesis of some derivatives of indoles

Catalysis represents the cornerstone of chemistry, since catalytic
processes are ubiquitous in almost all chemicalprocesses
developed for obtaining consumer goods. Nanocatalysis represents
nowadays an innovative approach toobtain better properties
for the catalysts: stable activity, good selectivity, easy to
recover, and the possibility to bereused. Over the last few years,
for the obtaining of new catalysts, classical methods—based
on potentialhazardous reagents—have been replaced with new
methods emerged by replacing those reagents with plantextracts
obtained in different conditions. Due to being diversified in
morphology and chemical composition, thesematerials have
different properties and applications, representing a promising
area of research. In this context, thepresent review focuses
on the metallic nanocatalysts’ importance, different methods
of synthesis with emphasis tothe natural compounds used as
support, characterization techniques, parameters involved
in tailoring thecomposition, size and shape of nanoparticles
and applications in catalysis. This review presents some examples
ofgreen nanocatalysts, grouped considering their nature
(mono- and bi-metallic nanoparticles, metallic oxides,sulfides,
chlorides, and other complex catalysts).
