Carbon nanotubes based nanostructured catalysts for water electrolysis and fuel cells

Abstract

CNTs composed of 2-7 tubes show significantly better activity for oxygen evolution, and exhibit better ability for hydrogen evolution and oxygen reduction. The better activity of these CNTs is result from the electron transfer pathway through tunneling effect, which makes them favorable materials to develop photo catalysts for water oxidation. Metal-CNTs hybrids with high activity and stability developed here provide new opportunities to develop catalyst with enhanced performance, better durability and low costs.
