Nanoparticle TiO2 has been shown to be effective in photocatalytically degrading aqueous contaminants ranging from organics and microbiologicals to heavy metals.  For most applications, the TiO2 must be deposited onto the surface of a support material.  A porous support material allows for a much greater photocatalytic surface area, and provides the ability to utilize flow-through membrane reactor configurations.  Existing surfactant-mediated methods for the fabrication of porous poly(methylmethacrylate) membranes have been modified to incorporate the deposition of TiO2 throughout the porous membrane. These materials exhibit excellent photocatalytic activity.  Incumbent methods for TiO2 deposition have utilized an undesirable dependence on organic solvents such as dichloromethane.   These porous composite membranes represent a much greener approach to TiO2-acrylic materials fabrication, and possess a photocatalytic activity which is over two times greater than the conventional non-porous materials.
