The electrodeposition of metallic phases, also known as electroplating, has been rigorously studied since its inception in 1805, yielding a great deal of fundamental knowledge and numerous practical products (e.g., corrosion-resistant coatings, catalysts, and consumer goods). Following the nano-revolution in the mid-20th century, prodigious resources have been devoted to control the surface coverage, size, and elemental composition of metal nanoparticles, which represent the functional unit of an electrodeposited film. These efforts aim to overcome the tendency for nanoparticles to nucleate and grow on energetically favorable surface sites, diffusion-layer overlap between neighboring particles, and variation in ion reduction kinetics, phenomena which result in coverage, size, and stochiometric heterogeneity, respectively. This dissertation describes a method termed nanodroplet-mediated electrodeposition, wherein the electrodeposition reaction is confined within single aqueous nanodroplets. By emulsifying precursor-loaded aqueous nanodroplets into an immiscible solvent such as 1,2-dichloroethane, nano-reactors may be generated which, upon collision with an electrode surface, undergo electrodeposition to form single nanoparticles with relative control over coverage and size compared to classical electrodeposition. The addition of a viscous component (e.g., glycerol) to the nano-reactors permits the quantification of single nanoparticle growth kinetics as the electrochemical signal is monitored using stochastic collisions at ultramicroelectrodes. Furthermore, the addition of multiple metal precursors to the nano-reactors allows multi-metallic high-entropy nanomaterials to be synthesized, which may be practically applied for bifunctional water electrolysis. Thus, novel fundamental knowledge and practical materials have been generated by this method, highlighting its promise to elucidate new and useful truths of nature in the near future.
