Fuel from CO2, titanium dioxide and sunlight?

oxygen molecules absorb on tio2 change
their state easily under the influence
of electric field
using a sharp tip we can both image and
alter the absorb co2 molecules in a well
controlled fashion theoretical
calculations show that oh to absorb on
the anatase 101 surface induces
structural changes in the oxide in
particular subsurface oxygen vacancies
migrate towards the surface it happens
either spontaneously or with the help of
the tip electric field it has been known
for about 40 years that the field
induced migration of oxygen vacancies is
critical in many applications however
direct imaging and detailed
understanding of the process is just
