The photoreduction of cytochrome c(3) using ZnTPPS as photosensitizer
was investigated and the photoinduced hydrogen evolution with hydrogen
ase using cytochrome c(3) as electron carrier was established. The que
nching of photoexcited tripler state of ZnTPPS with cytochrome c, was
measured and the rate constant was 1.2 x 10(9) M(-1)s(-1)(1M=1 mol dm(
-3)).
