Morphological control of ZnS nanopowders by different capping molecules

Complex 3D architectures of ZnS microflowers have been successfully synthesized via a quick water-based precipitation synthesis method at moderate temperature (<100 °C) using an inorganic capping agent K2S2O7. The synthesized samples were characterized by SEM, XRD, FTIR and BET analysis. The as-synthesized ZnS microflowers are composed of numerous nanowires and has a cubic structure. Surface area is 42 m2·g−1 and the pore diameter is 3.7 nm. Comparison with equivalent synthesis with an organic capping agent (PVP) was performed.
