In recent years, copper-based nanomaterials are opening up new frontiers in fundamental research and applications in energy and environmental sustainability. Colloidal synthesis methods to metal nanostructures are highly desirable because of their scalability, reproducibility, structural tunability and low-cost. Compared to noble metals such as gold and silver, shape-controlled synthesis of copper-based nanocrystals is much less developed. In this talk, I will share our group’s recent progress on the synthesis of shape-controlled multimetallic copper-based nanocrystals utilizing a heterometallic seed-mediated synthetic approach. Monodisperse shape-anisotropic nanocrystals such as nanorods, prisms and polyhedra can be accessed using pre-formed Au nanocrystal seeds. I will further discuss our strategies that provide orthogonal control over nanocrystal shape and multimetallic distribution. These well-defined nanomaterials are promising electrocatalysts for high-rate, high selectivity reduction of carbon dioxide to liquid fuels.
