Enhanced photoelectrochemical activity of Co-doped β-InS nanoflakes as photoanodes for water splitting.

This work is primarily focused on indium sulfide (β-InS) and cobalt (Co)-doped β-InS nanoflakes as photoanodes for water oxidation. The incorporation of cobalt introduces new dopant energy levels increasing visible light absorption and leading to improved photo-activity. In addition, cobalt ion centers in β-InS act as potential catalytic sites to promote electro-activity.
