在胶体PbS纳米片的合成中，反应溶液的上清液被重复使用以提高铅的转化效率。它使铅前体到PbS纳米片的转化效率加倍。通过再利用上清液合成的纳米片具有与原始纳米片相似的形态、几乎相同的厚度和光学性质，这通过透射电子显微镜、X射线衍射和光致发光光谱来证实。该方法减少了合成过程中有毒的含Pb废物，这是迈向胶体2D PbS纳米片的绿色和可规模化合成的一步。
In the synthesis of colloidal PbS nanosheets, the supernatant of the reaction solution is reused to boost the lead conversion efficiency. It doubles the conversion efficiency of the lead precursors to the PbS nanosheets. The nanosheets synthesized by reusing the supernatant have similar morphology, nearly identical thickness, and optical properties as the original ones, confirmed by transmission electron microscopy, X‐ray diffraction, and photoluminescence spectroscopy. This method reduces the toxic Pb‐containing waste during the synthesis, a step toward the green and scalable synthesis of colloidal 2D PbS nanosheets.
