ABSTRACT: Recently we have focused on the architecture engineering of inorganic nanomaterials for their applications to fuel cell electrocatalysis, lithium ion battery, and photocatalysis. We present a synthesis of highly durable and active electrocatalysts based on ordered fct-PtFe nanoparticles for ORR electrocatalysts for fuel cells. We report on the design and synthesis of highly active and stable Co-N4(O) moiety incorporated in nitrogen-doped graphene (Co1-NG(O)) for electrochemical H2O2 production. We report on the design and synthesis of highly active TiO2 photocatalysts incorporated with site-specific single copper atoms (Cu/TiO2) for photocatalytic hydrogen generation activity. We synthesized multigrain nanocrystals consisting of Co3O4 nanocube cores and Mn3O4 shells. We fabricated ultraflexible/stretchable electronic devices integrated with various functional nanomaterials and their applications to wearable and implantable medical and healthcare devices. We introduced electromechanical cardioplasty using an epicardial mesh made of electrically conductive and elastic Ag/Au nanowire-rubber composite material.
