Asymmetric Structure Awakened n-π* Electron Transition in Sulfur and Selenium Co-doped g-C3N4 with Efficient Photocatalytic Per-formance
文献摘要：
Sulfur and selenium co-doped graphitic carbon nitride (SSCN) with efficient pho-tocatalytic activity was synthesized by synchronously introducing sulfur and selenium atoms into the melon structure of g-C3N4 (GCN) via a facile solid-phase thermal reaction of GCN and SeS2. The as-prepared SSCN possesses a larger specific surface area with a richer pore structure that provides more active centers for catalytic reaction. More importantly, the asym-metric structure of SSCN due to introducing sulfur and selenium not only maintains an easier activation of π-π* electron transition but also awakens the n-π* electron transition in g-C3N4. Moreover, the n-π* electron transition of SSCN can be controlled through changing the amount of SeS2, which can greatly extend the photo-response range to 600 nm. As a result, the SSCN samples show an excellent photo-degradation performance for typical antibiotic of tetracycline hydrochloride (TC). The specific degradation route and main intermediates of TC based on liquid chromatograph mass spectrometer (LC-MS) analysis are also investigated and discussed.
