Engineering nanocrystals with size, shape, composition, structure and strain control is the key to enhance the performance of energy conversion devices. In this talk, I will focus on my recent advances in making/tuning high-quality metal-based nanocrystals for boosting the electrocatalysis of fuel cells and solar fuels. I will start with several examples on how to tune the surface and interface of multimetallic nanocrystals for achieving more efficient oxygen reduction electrocatalysis. Then, I will move to tune the defects and high-index facets of multimetallic nanocrystals for boosting the liquid fuels oxidation catalysis. Finally, I will discuss how to introduce the interface of metal-based materials for highly efficient hydrogen evolution reaction.
