Concurrent photocatalytic and filtration processes using doped TiO2 coated quartz fiber membranes in a photocatalytic membrane reactor

Titanium dioxide (TiO2) composite fiber membranes were prepared by means of sol-gel dip coating methods and were subsequently tested in a photocatalytic membrane reactor (PMR) experiment that incorporated two pollutant removal processes: dead-end filtration and photocatalytic degradation. TiO2 nanoparticle suspensions were initially prepared using the sol-gel synthesis. Quartz fiber filters were immediately dip coated with undoped and doped …
