Photocatalytic reactions of alkenes over TiO2-adsorbed water have been investigated.The products are hydrogenated molecules (CnH2n+2) formed by the addition of two H atoms to the ? bond of the alkene (CnH2n, 2 H and (kHkOH)1/2, respectively.Here, kH and kOH are rate constants for addition of H atoms and OH radicals to alkene in the vapour phase.For photocatalytic isomerizations, it is found that the isomerization of (E)-but-2-ene to but-1-ene (trans form) which has the same geometrical form is about twice as effective as that between (Z)-but-2-ene and but-1-ene and that the addition of OH to the C(1) position of but-1-ene prevents the isomerization to but-2-enes.
