A vertically aligned carbon nanotube/fiber based electrode for economic hydrogen production by water electrolysis

This paper presents a novel approach to maximize the current density of electrodes modified by carbon nanotubes for high efficiency hydrogen production. Multiwalled carbon nanotubes (MWNTs), due to their unique electrical conductivity and mechanical properties, have led to our interest in their application of MWNTs for water splitting purposes. The motivation for this work is to provide a platform which outperforms the traditional industrial material-graphite while still being compatible with the integration of other emerging technologies. These also require robustness in structure and performance in different electrolytes, and stability and reproducibility in the long term. In addition, it should be economically viable. The proposed graphite-MWNTs electrodes have been fabricated and tested in various conditions. Finally, performance and sustainability have been demonstrated.
