Abstract
A process for the production of durable photocatalytically active self-cleaning coating on glass by contacting a hot glass surface with a fluid mixture of titanium chloride, a source of oxygen and a tin precursor. The coating preferably comprises less than 10 atom % tin in the bulk of the coating and preferably there is a greater atomic percent tin in the surface of the coating than there is in the bulk of the coating. Preferably, the coating is durable to abrasion and humidity cycling.
