Photolytic reduction of CO2 and Water to CO and H2

[Peanuts]

Hey all,
Great forum! Loved all the discussions here

 

Now, I went through a research paper from RSC where they have Reduced CO₂ and Water to CO and H₂ gas via Solar energy. Is this really feasible in the long run? Because, the Products or Syn Gas is used to make Gasoline via the Fisher Tropsch process. So that would mean unlimited fuel right without global warming, right?

Also, to add, it used a Ruthenium Complex. That could be a downer. Isn't Ruthenium way expensive?
