Abstract
Titanium dioxide is hard to coat on glass or boehmite at low pH. In this study, a method to coat titanium dioxide functionalized by Ag on the glass surfaces using a Cu-containing solution is proposed. This method facilitated the coating of titanium dioxide functionalized by Ag on glass surfaces using 3-aminopropyltrimethoxysilane (APTMS). Results showed that Ag–TiO2 nanoparticles can be coated on Al and glass surfaces. Furthermore, they can be coated on boehmite at low pH without using APTMS.
