The design and creation of a sustainable green source of energy with a high performance is highly important. There are many approaches for this goal, and one of promising alternative energy technologies should be batteries and fuel cells. Precious metals, such as Pt and Ir, have been used as catalyst materials for fuel cells for cars and stationary power generation, water splitting, etc.; however, such metals are expensive and not earth-abundant elements. The replacement of such precious metal-based electrocatalysts with low-cost materials is crucial for the next generation sustainable energy society. This minireview focuses on nanocarbons, especially carbon nanotubes, for use in the preparation of non-precious metal catalysts for fuel cells, oxygen reduction, oxygen evolution, hydrogen evolution, water splitting and Zn-air battery with a high performance.
