PbSe[at]PbSO sub(4) nanoparticles: sonochemical synthesis and characterization and its photocatalytic degradation of methylene blue

For the first time PbSe-core/PbSO sub(4)-shell nanoparticles were prepared through a simple sonochemical method with aid of SeCl sub(4) and [bis(2-hydoxyacetophenato)lead(II)]; [Pb(HAP) sub(2)]; as starting precursors. According to authors knowledge, for the first time [Pb(HAP) sub(2)] complex is used as lead source for the synthesis of PbSePbSO sub(4) nanoparticles. Sodium lauryl sulfate was played role as surfactant and sulfur precursor to produce PbSePbSO sub(4) nanoparticles. PbSe nanoparticles are uniformly coated on the whole surface of PbSO sub(4). Moreover, a possible reaction mechanism of the formation of PbSePbSO sub(4) nanoparticles has been discussed. Furthermore, the efficiency of PbSePbSO sub(4) nanoparticles as a photocatalyst for the decolorization of methylene blue using visible light irradiation has been evaluated. The as-prepared PbSePbSO sub(4) nanoparticles were extensively characterized by techniques such as XRD, EDX, TEM, SEM, PL, and FT-IR.
