Many attention has been focused on the development of non-precious metal-based electrocatalysts for fuel cells and batteries with high performance, durablity, and scalability for the next-generation eco-friendly energy society[1-3] in order to reduce the cost of the catalysts.

In this meeting, we present a method to fabricate nanocrystals of metal oxides on carbon nanotube surfaces, which was carried out based on the recent finding that pristine multi-walled carbon nanotube/iron phthalocyanine hybrids with a well-defined nanostructure showed an excellent efficiency and durability for oxygen reduction reaction[2], as well as decorating unoxidized-carbon nanotubes with homogeneous Ni-Co spinel (and related) nanocrystals showed a superior performance for oxygen evolution/reduction reactions[3].
