Liquid phase synthesis is a powerful method for the formation of uniform sized nanoparticles and nanoparticles with a faceted morphology. General strategies for the formation of nanoparticles and through chemical synthesis will be outlined. The use of ligand binding is an important strategy to control the growth and final shape of nanocrystals and will be discussed. The results presented will include the formation of catalytic metals such faceted and branched nanostructures containing gold, palladium and ruthenium. The growth mechanism of how the particles form will also be presented along with HRTEM observations. Catalytic applications will be discussed with a focus on branched ruthenium based systems for electrocatalysis of the oxygen evolution reaction shown below.
