Abstract
The composites of silica-titania that have consolidant and self-cleaning property have been synthesized by mixing titania and colloidal silica. The coating of stone using silica-titania could improve the mechanical properties of andesite stone. In addition, the coating created the superhydrophilic properties and similar visual appearance with untreated andesite. The self-cleaning performance of treated andesite could remove the 92% of congo red and 67% of methylene blue as staining agents through photocatalysis process.
