本文采用简单烧结工艺制备了W(NxS1−x)2纳米花。光催化活性结果表明，我们制备的n掺杂WS2纳米花在可见光下具有良好的降解罗丹明B的光活性。这主要是由于光致电子-空穴对分离效率高，价带（VB）变宽，能带隙变窄。同时，我们的工作提供了一种通过引入杂质原子来诱导晶体表面硫空位以增强其光降解的新方法。
Here, W(NxS1−x)2 nanoflowers were fabricated by simple sintering process. Photocatalytic activity results indicated our fabricated N-doped WS2 nanoflowers shown outstanding photoactivity of degradating of rhodamine B with visible light. Which is attributed to the high separation efficiency of photoinduced electron–hole pairs, the broadening of the valence band (VB), and the narrowing of energy band gap. Meanwhile, our work provided a novel method to induce surface sulfur vacancies in crystals by introduing impurities atoms for enhancing their photodegradation.
