Abstract
For the first time PbSe-core/PbSO4-shell nanoparticles were prepared through a simple sonochemical method with aid of SeCl4 and [bis(2-hydoxyacetophenato)lead(II)]; [Pb(HAP)2]; as starting precursors. According to authors knowledge, for the first time [Pb(HAP)2] complex is used as lead source for the synthesis of PbSe@PbSO4 nanoparticles. Sodium lauryl sulfate was played role as surfactant and sulfur precursor to produce PbSe@PbSO4 nanoparticles. PbSe nanoparticles are uniformly coated on the whole surface of PbSO4. Moreover, a possible reaction mechanism of the formation of PbSe@PbSO4 nanoparticles has been discussed. Furthermore, the efficiency of PbSe@PbSO4 nanoparticles as a photocatalyst for the decolorization of methylene blue using visible light irradiation has been evaluated. The as-prepared PbSe@PbSO4 nanoparticles were extensively characterized by techniques such as XRD, EDX, TEM, SEM, PL, and FT-IR.
