Zinc sulfidation by H2S and H2S/H2O supercritical fluids: Synthesis of nanoparticles and catalytic effect of water

- Sulfidation of Zn plates by H2S and H2S/H2O supercritical fluids is studied.
- At zinc sulfidation by hydrogen sulfide ZnS nanoneedles are formed.
- ZnS and ZnO nanoparticles are formed in H2S/H2O supercritical fluid.
- Catalytic effect of water on zinc sulfidation is observed.
