I prepared NiS2- metal dichalcogenide?

28 September 2024 0 3K Report

Using a hydrothermal, I dissolved 2mmole of Ni (NO3) 2.6H2O and 4mmole of Thiourea under stirring and sonication in 40ml DIW. I kept it at 160C for 24 hours. After cooling, I got only green liquid. The gray precipitate is not remarkable. Where is my mistake? In the amount of the precursors or what?
