| In our research project we are designing a mesoporous silica gel pellet capable of providing a titania photocatalyst contact with water impurities, as well as allowing UV light penetration. We are also beginning to use a dopant to allow visible light to activate the reactor. Two methods are being developed for silica pellet formation. One includes a dusting method that would allow us to coat the pellets as they are being formed, which would eliminate the need for surface pores for titania addition. This is accomplished by coating the wells used for pellet formation prior to the addition of our silica gel. The other method is development of silica gel pellets with adequate surface pores for the addition of titania impregnated SBA-15. Both provide the uneven distribution of titania over the surface, as well as UV light penetration. We are currently optimizing the production techniques for efficiency, as well as accuracy in reproduction. |
