Porous ’coral-like‘ TiO2 structures produced by templating polymer gels.

摘要: A new synthetic approach to generate highly porous semiconductor networks that could be used for catalytic and solar cell applications is reported. Titanium dioxide were produced using a polymer gel templating procedure, resulting in coral-like structure with wall thickness of about 100−150 nm pore sizes ranging from 100 micrometers diameter. Calcination results the production either anatase or rutile crystal phases without carbon contamination starting materials, individual titanium particles contacting neighbors, thereby forming continuous network. The obtained are importance various fields research as open “coral-like” network allows high access surface reaction medium.
