Simple synthesis, characterization and investigation of photocatalytic activity of NiS2 nanoparticles using new precursors by hydrothermal method (original) (raw)

This research focuses on the synthesis, characterization, and photocatalytic activity of NiS2 nanoparticles using novel precursors through a hydrothermal method. The study successfully synthesizes high-purity single-phase NiS2 nanostructures using [Ni(pht)(H2O)2] and cysteine as precursors while examining the influence of various sulfur sources. The resulting NiS2 nanoparticles exhibit a band gap of approximately 2.2 eV, indicating their potential as semiconductors for photocatalysis. Photocatalytic efficiencies showed a dye degradation of 57% for Erythrosine and 71% for Phenol red under UV irradiation.
