The importance of nanotechnology to freely control materials at the atomic and molecular scale (10-9m=1nm (nanometer)) is increasing for development such as catalysts that enable material conversion for realizing a sustainable recycling society and electronic materials that miniaturize devices around us. Since I learned that everything is made up of a combination of various atoms in my junior high school, I have been interested in chemistry which allows creating materials by controlling atoms. So far, I have been studying the synthesis of nano-sized metal particles (metal nanoparticles) using chemical methods and their catalytic application. In the Hakubi Project, I will promote basic research on multi-element nanoalloys, their efficient development methods, and applications as catalysts, which leads to developing new nanomaterials that would play a role in future society.
