Photocatalytic activity

This paper aims to examine the separation of ultrafine titanium dioxide (TiO2) ptotocatalyst from its aqueous suspensions and its reuse by cross-flow ultrafiltration (CFU) process. Initially, the effects of various parameters, such as feed concentration, transmembrane pressure, cross-flow velocity,

Fine particles of photoactive anatase-type TiO2 were loaded on activated carbon and carbon spheres through the hydrolysis of titanium oxysulfate under autogenous hydrothermal conditions. Their photoactivity and adsorptivity were evaluated separately by the measurements of relative concentration of m
