Overview for multimetallic nanostructures with biomedical, environmental and industrial applications

Multimetallic nanostructures acquired a prominence in technological advancements due to their enhanced optical, electronic, chemical, and magnetic properties for various applications which were correlated to their morphological features and elemental structures. Multimetallic nanostructures were extensively attracted attention of researchers compared to their corresponding monocular metallic nanostructures in both scientific and technological view. There were two main synthetic strategies for production of multimetallic nanostructures which were named as simultaneous (ex., co-reduction, thermal decomposition, radiolysis and sonochemical synthesis) and successive methods (seed-mediated growth). The geometrical shape of the multimetallic nanostructure was strongly dependent on two main factors; the synthetic strategy and its particular elemental composition. Multimetallic nanostructures were well known to be synthesized in four geometrical shapes; random, cluster -in-cluster, core-shell, and nano-alloys. The current review represents an overview for the synthetic strategies, stabilization strategies, and different types of multimetallic nanostructures based on metals from which multimetallic nanostructures were nucleated. Additionally, their superior applications in medical, environmental and industrial purposes were also summarized. (C) 2020 Elsevier B.V. All rights reserved.
