Enhanced photoelectrochemical activity of Co-doped β-In₂S₃ nanoflakes as photoanodes for water splitting.

ABSTRACT: This work is primarily focused on indium sulfide (β-In₂S₃) and cobalt (Co)-doped β-In₂S₃ 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-In₂S₃ act as potential catalytic sites to promote electro-activity. 5 mol% Co-doped β-In₂S₃ nanoflakes when tested for photoelectrochemical water splitting exhibited a photocurrent density of 0.69 mA cm^-2 at 1.23 V, much higher than that of pure β-In₂S₃.
