The enhanced photocatalystic activity in FeS/WS2 nanosheets with a charge separation effect
FeS/WS2 nanocomposites were synthesized by sulfurizing Fe2O3/WO3 powders obtained by a hydrothermal method. Many WS2 nanosheets with a thickness of less than 5 nm are scattered from a same center to form a flower-like microsphere while these FeS nanoparticles are attached to these WS2 nanosheets. Wh...

| Summary: | FeS/WS2 nanocomposites were synthesized by sulfurizing Fe2O3/WO3 powders obtained by a hydrothermal method. Many WS2 nanosheets with a thickness of less than 5 nm are scattered from a same center to form a flower-like microsphere while these FeS nanoparticles are attached to these WS2 nanosheets. When used as the photocatalyst, these FeS/WS2 nanocomposites have excellent activity under UV irradiation, which can be attributed to the large specific surface area and the charge separation effect in these two materials. So this paper shows a simple method to synthesize two-dimensional sulfide heterojunction for effective photocatalysis. |
