Photocatalytic cyclopentane deuterium isotope exchange

Photocatalytic cyclopentane-deuterium isotopic exchange (CDIE)... [Pg.204]

That products of intermediate oxidation level can be detected in the photocatalytic reactions of hydrocarbons and fossil fuels is also consistent with a surface bound radical intermediate . Photocatalytic isotope exchange between cyclopentane and deuterium on bifunctional platinum/titanium dioxide catalysts indicates the importance of weakly adsorbed pentane at oxide sites. The platinum serves to attract free electrons, decreasing the efficiency of electron-hole recombination, and to regenerate the surface oxide after exchange. Much better control of the exchange is afforded with photoelectrochemical than thermal catalysis > ) As before, hydrocarbon oxidations can also be conducted at the gas-solid interface... [Pg.88]

The photocatalytic isotopic exchange between cyclopentane and deuterium (CDIE) was carried out in a static fused silica photoreactor described in ref (23),... [Pg.201]
