Chromium Selenide Nanoparticles: Hydrothermal Synthesis in the Presence of a New Selenium Source

Chromium selenide (Cr2Se3) nanoparticles were prepared by hydrothermal method from Cr(NO3)3.9H2O and SeCl4 as precursors. These nanoparticles could be produced simply in the presence of cetyltrimethyl ammonium bromide, sodium dodecyl sulfate and polyethylenglycole 600 (PEG600) and 4ml of hydrazine hydrate (N2H4.H2O) at 180 ˚C for different times. By varying the reducing agent to potassium borohydride (KBH4), agglomerated structures with different morphologies were produced. The effects of surfactant, reducing agent, reaction time and temperature on the morphology of the products was investigated.
