  • Frontiers | Optimization of Sulfurization .

    During the pyrolysis process of the S-Co-N/C-I after sulfurization, the induced oxygen was first reacted with the metal atoms to form metal oxides. As the pyrolysis temperature increased, the metal oxides would be gradually reduced to metal atoms by the generated carbon. At the same time, the oxygen-containing species were removed out from the material.

  • Effects of Sulfurization Pressure on the .

    At low pressures, the melting point of metal sulfides decreases during the sulfurization process and so liquid Cu 2 S may help to increase the grain size . Also, due to different diffusion coefficients of the elements the Kirkendall effect can be observed during low pressure sulfurization. That brings about the formation of voids and secondary phases like SnS, Cu
