The synthesis of compound chalcogenide nanoparticles – containing sulfur, selenium, or tellurium as the anion – is a robust research field. Many solution-based synthesis routes are well established for transition metal chalcogenide compounds for a number of binary and multinary materials. However, one area in which research is lacking is the solution-based synthesis of group 4 (Zr, Hf, Ti) chalcogenide materials. One challenge in particular is a high affinity for oxidation for these group 4 elements. Many possible synthesis routes are available for these materials, including hot injection and thermal decomposition. Of the group 4 chalcogenides, zirconium sulfide (ZrS2) is of particular interest due to its semiconducting properties. To further study this material, we have conducted various solution-based syntheses. In this work we report an overview of the synthetic routes for ZrS2 synthesis from several techniques, and the challenges faced by these methods. Throughout these experiments we have noticed a trend where zirconium oxide (ZrO2) forms much more favorably than ZrS2. We also propose future work that could resolve these issues.
