文摘
- •
Bi2S3/Bi2WO6 hybrids with exposed (020) Bi2WO6 facets have been synthesized.
- •
X-ray photoelectron spectroscopy reveals that a small amount of Bi2S3 was formed.
- •
The enhanced photoactivity of hybrids is due to heterojunction and (020) facets.
- •
A possible photocatalytic degradation mechanism is proposed.
