Revolution from monometallic to trimetallic nanoparticle composites, various synthesis methods and their applications: A review

摘要

Trimetallic nanopartides are mainly formed by the combination of three different metals. The trimetallic catalysts were considerably more professional than bimetallic one. The trimetallic and bimetallic nanopartides are of enormous attention than that of monometallic in both technological and scientific view as in these nanopartides the catalytic properties can be tailored better than that of in the single monometallic catalyst. The trimetallic nanopartides have been synthesized by different methods such as microwave, selective catalytic reduction, micro-emulsion, co-predpitation and hydrothermal etc. The surfaces area of trimetallic nanopartides is comparatively unstable and thus gets simply predpitated away from their solution and ultimately resulted in their reduced catalytic activity. By using stabilizers like block copolymers, organic ligands, surfactants and dendrimers the trimetallic nanopartides can be stabilized. The nanocomposites of trimetallics have been synthesized with inorganic and organic compounds such as: carbon, graphene, gelatin, cellulose, starch, chitosan, alginate, collagen and A1_2O_3 etc. Trimetallic nanopartides are used as a catalyst due to their outstanding electrochemical catalytic activity in comparison with the monometallic or bimetallic nanopartides.
