| 1. A process for a producing a coated float-glass substrate, comprising:
chemical vapor depositing at least one titanium precursor on at least part of at least one face of a float-glass substrate
produced in a float-bath chamber, to produce a photocatalytic coating containing at least partially crystalline titanium oxide,
wherein the crystalline titanium oxide is in the form of crystallites with an average size of between 0.5 and 60 nm.
