Реферат:
To verify a hypothesis about the electronic state of diatomic gaseous sulfur formed during the lowtemperature
catalytic decomposition of hydrogen sulfide, we carried out some experiments to examine
elemental sulfur dissociation. As shown, after heating at ∼1000 K, elemental sulfur sealed in quartz
ampoules with metal catalysts followed by quenching at room temperature did not produce any visible
changes on solid sulfur. However, conversion of solid sulfur into gaseous diatomic sulfur can be realized
via intermediate interaction of melted sulfur with hydrogen in the presence of Pt followed by decomposition
of H2S formed on the surface of the metal catalyst at room temperature. It is suggested that the
conversion of the singlet sulfur atoms into the ground triplet state becomes feasible only on the surface of
metal catalysts resulted from the dissociation of hydrogen sulfide into adsorbed atomic species.
