[EN] Splitting of hydrogen sulfide is achieved to produce valueadded
chemicals. Upon irradiation at 254 nm in the gas phase
and in the absence of catalysts or photocatalysts at near room
temperature, H2S splits into stoichiometric amounts of H2 and
S with a quantum efficiency close to 50%. No influence of the
presence of CH4 and CO2
(typical components in natural gas
and biogas in which H2S is an unwanted component) on the
efficiency of overall H2S splitting was observed. A mechanism
for the H2 and S formation is proposed.
