Synthesis and Applications of Bimetallic Nanoparticles of Immiscible Elements

Recent advances in nanotechnology make it possible to create nanomaterials with novel microstructure and unique physicochemical properties. Different structures of nanoparticles of immiscible elements can be synthesized using chemical, mechanochemical or physical methods. The present review is devoted to contemporary state of the studies on the methods to produce bimetallic nanoparticles formed of immiscible metals.

We undertook a structured search of bibliographic databases for peer-reviewed research literature using a focused review question and inclusion/exclusion criteria. The quality of retrieved papers was appraised using standard tools.

Ninety-six papers were included in the review. Taking into account a large number of works in this field of the studies in the present review we are going to consider general methods of producing BMINPs with diverse structures: core-shell (twenty one papers), nanoalloys (twenty papers), Januslike (sixteen papers). The field of BMINPs application was described in seventeen articles. In the part Current & Future Developments the perspectives on the usage of bulk materials produced by BMINPs consolidation are discussed.

As can be seen from this review, ideal bimetallic nanoparticles synthesis methods are not developed by now. The existence of different routes to nanoparticles synthesis and their unique properties confirm the importance promoted awareness of potential benefits of nanoparticles in different applications. The reviewed patents emphasized the importance of bimetallic nanoparticles and their application in various fields as well.
