Successive ionic layer adsorption and reaction (SILAR) process has been diversely used for deposition of various metal chalcogenides. SnS is one of them. Owing to the under-utilization of ionic precursor used in SILAR process, recovery of ionic species from solvents is important and critical before disposal. Since a variety of solutes and solvents can be used for the deposition of SnS, we have devised a comparison revealing the diversity of SnS. It is revealed that the residual cationic precursors play an important role in deciding the eventual morphology, purity and thus the photocatalytic performance of nanostructured SnS. We directly compared SnS nanostructures salvaged from ionic precursors of SnSO₄ and SnCl₂ under similar salvaging conditions and ensued that flower-like SnS can be obtained successfully. Intensive scanning electron microscopy and energy dispersive spectroscopy were utilized to have a closer check on the evolution of morphological and compositional characteristics. Rhodamine B and methylene blue dyes were successfully degraded by both types SnS, however SnS@SnCl₂ exhibited superior performance which was credited to its unique flower-like morphology. Significantly, ~ 96.3% removal of methylene blue dye from water was achieved in only 40 min.

连续离子层吸附和反应 (SILAR) 工艺已广泛用于各种金属硫属元素化物的沉积。SnS 就是其中之一。由于 SILAR 工艺中使用的离子前体未得到充分利用，因此在处置之前从溶剂中回收离子物质是重要且关键的。由于多种溶质和溶剂可用于 SnS 的沉积，我们设计了一个比较来揭示 SnS 的多样性。结果表明，残留的阳离子前体在决定纳米结构 SnS 的最终形态、纯度以及光催化性能方面起着重要作用。我们直接比较了从 SnSO ₄和 SnCl _{2 的}离子前体中回收的 SnS 纳米结构在类似的回收条件下，可以成功获得花状的 SnS。密集扫描电子显微镜和能量色散光谱被用来更仔细地检查形态和成分特征的演变。两种类型的 SnS 均成功降解了罗丹明 B 和亚甲蓝染料，但 SnS@SnCl ₂表现出优异的性能，这归功于其独特的花状形态。值得注意的是，仅在 40 分钟内即可从水中去除约 96.3% 的亚甲蓝染料。
