derivatives have been reported. Some of them were used as precursors for inorganic nanocomposites. The discussed nanomateri-
als have been synthesized by classic wet chemistry routes, as well as by sonochemical and solvothermal processes, electropoly-
merization, the sol-gel method, and so on.
The obtained nanocomposites possess properties frequently better in comparison with their nonnano analogues and have
numerous environmental applications, in particular the removal, recovery, concentration, or separation of heavy/toxic (Cr 3+ ,
Co 2+ , Ni 2+ , Cu 2+ , Cd 2+ , Pb 2+ and As 3+ ) and rare metals from natural and industrial waters and the elimination of bacterial patho-
gens ( E. coli ) from water, also being sensors for metal cations, nanosorbents, and composing fuel cells. They can also serve as
catalysts (hydrodechlorination) or photocatalysts (degradation of phenol or MB). Despite these applications, coordination and
organometallic nanomaterials have a limited number of applications in the field of environmental protection.
