Abstract:
The present invention provides: a mesoporous silica composite powder comprising a mesoporous silica molecular sieve and a titanium dioxide (TiO2) coating layer on the silica molecular sieve; and a production method for the same. According to the mesoporous silica composite powder coated with titanium dioxide of the present invention, a precursor solution is used in a lesser amount than in existing methods for synthesizing titanium dioxide, and thus the present invention is economical. Silica particles of which the form and size can be adjusted are previously produced, a titanium dioxide film is formed thereon, thereby securing a wide-range ultraviolet screening performance and an outstanding ultraviolet screening performance.
