Bimetallic Nanocrystals: Growth Models and Controlled Synthesis

In recent years, improvements in the fundamental understanding of synergistic effect between two distinct metal elements in bimetallic nanocrystals have started to revolutionize the development of alternative energy systems for clean energy production, storage, and conversion. By using an interdisciplinary approach that combines both experimental and computational methods, the scientists are possible to rational-design and predict the properties that can enhance the performance of bimetallic nanocrystals for required applications. Although the choice of metal elements is an important aspect of bimetallic nanocrystals, their structures (e.g., core-shell, dendrite, and alloy) are a concern for nearly all bimetallic nanocrystals’ applications. This chapter will mainly describe the influence of bimetallic structures for the applications and their related synthetic strategies, aiming to provide guidance to rationally design and synthesize bimetallic nanocrystals with desired properties.
