✦ Synopsis

A new H2S decomposition process using solar energy is proposed in order to achieve solarto-chemical energy conversion. As shown below, the process consists of absorption of HES with 12aq and photoelectrochemical decomposition of the resulting HIaq.

H2S(g) + 12aq--~ 2HIaq + S(s)

hv 2HIaq ~ H2(g) + I2aq

overall: H2S(g)--," H2(g) + S(s)

The process is compared with a photocatalytic H2S decomposition process and with simple photoelectrochemical HIaq decomposition process.
