摘要

This work is primarily focused on indium sulfide (beta-In2S3) and cobalt (Co)-doped beta-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 beta-In2S3 act as potential catalytic sites to promote electro-activity. 5 mol% Co-doped beta-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 beta-In2S3.
