I am interested in the potential photo-properties of precious metal oxides, say PtO2, AgO, RuO2or IrO2 nanoparticles, concerning their band gaps/edges. Comments, information, or literatures are appreciated.

Thanks Nathir. Unfortunately, this chapter does not involve precious metal oxides.
I can only write for AgO, as I don't have experience with the other metal oxides:
AgO/Ag2O absorbs the light and shows no scattering, also for large particles. For Ag/AgxO particles the absorption peaks of Ag are red-shifted and decrease in intensity.
Sources below for composite particles. I'd assume the other precious metal oxide particles would behave similar.

Thanks, Andreas.
This information is quite interesting to me.
If someone has any complementarities on RuO2 and IrO2, it would be great :)
RuO2 is reviewed in detail here, with some band edge information but no discussion of photoactivity:

An interesting report on IrO2 photocatalytic activity can be found here:
