Sonochemical synthesis of mass single-crystal PbS nanobelts

PbS nanostructures synthesized via surfactant assisted mechanochemical route

“…3) data the anisotropic growth character of nanocrystalline PbS can be confirmed. EDTA and Pb 2+ ions can form a very stable complex [22]. This steric stabilization has negative effect on the total specific area formation as observed in our experiments: the values 13.8 and 31.3 m 2 g -1 have been obtained for milling with and without EDTANa 2 •2H 2 O, respectively.…”

Synthesis and characterization of PbS crystals via a solvothermal route

“…Up to now, various shapes of PbS nano-and micro-crystals, such as nanoparticles [12], nanorods [13], nanaowires [14], hierarchical star-shaped PbS microcrystals [15], dendrites [16], flowers [17], nanobelts [18], ear-like crystals [19], have been prepared through various routes, including hydrothermal and solvothermal methods, microwave-assisted heating, ultrasonic irradiation, electrodeposition, template-assisted, and thermolysis of a singlesource precursor. Among them, the synthesis route from solutions is an especially powerful tool for the convenient and reproducible synthesis of PbS nano-and micro-crystals.…”

Growth of PbS microtubes with quadrate cross sections

“…The as-formed quadrate structure could serve as the preferential surface site for the stacking of the upcoming PbS building blocks. Considering the anisotropic growth character due to its inherent structure [33], subsequent axial growth leads to the formation of the faceted PbS microtubes with quadrate cross sections. The detailed mechanism for the formation of quadrate PbS microtubes is not fully understood and requires more systematic and extensive study.…”
