In this work, flower-like nanoparticles of lead sulfide (PbS) and metal-doped PbS nanostructures were synthesized via a simple hydrothermal method in water as a green solvent. The effect of temperature, precipitating agent and capping agent on the morphology and particle size of the products was investigated. Sugars were used as green, safe, cost-effective, and bio-compatible capping agents. The prepared products were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, and ultra violet-visible spectroscopy. The effect of PbS as a photocatalyst on the degradation of three different azo dyes was investigated. Acid brown, acid violet, and acid blue were totally degraded at 60 min under ultra-violet irradiation.
