Looks like Os is right.
Photoactivated oxidation by alcohols by oxygen.
J. Am. Chem. Soc. (1985), 107(21), 6116-17.
Ab.
A wide variety of alcs. can be selectively oxidized by two electrons at room temp. by O2 if a H2PtCl6/CuCl2 photocatalyst is used. The catalyst responds to visible light and is active in excess of 150 turnovers. Quantum yields for product formation as high as 0.1 have been obsd. using 488nm light. When primary alcs. are used as the substrate, aldehyde is formed in high yield with no appreciable overoxidn. to the acid. The catalytic cycle involves a Pt(III) species, which undergoes a redox reaction with Cu(II) to regenerate the Pt(IV) catalyst.
Photocatalytic dehydrogenation of liquid alcohols by platinized anatase.
J. Chem. Soc., Faraday Trans. 1 (1987), 83(5), 1631-9. Ab.
The photocatalytic dehydrogenation of liq. MeOH, EtOH, PrOH, and 2-PrOH was investigated using platinized anatase and 366 nm radiation over the range 278-303 K. Activities and activation energies for carbonyl-compd. formation were effectively identical for the alcs. on Pt(0.5)/TiO2 prepd. by photodeposition. The activation energy of 20 kJ mol-1 is assocd. with photoelectron transport through the anatase to the Pt particles. With Pt(0.5)/TiO2 prepd. by impregnation and H2 redn., identical activities for the 4 alcs. were achieved after O treatment.

Ah, excuse me, I think I may be mistaken.
Chloroplatinic acid selectivly catalyzes the liquid phase of ethanol to acetadehyd giving yelds exeeding 95%
Unless there is a way for the chlorine to be reduced back to revert back to the chloroplatinic acid, then the chloroplatinic acid cannot be considered a catalyst, by definition.
So, something either has to suck up the hydrogen from the chlorine/system, or chlorine is not the oxidant.
