CPC photocatalytic reactor in presence of immobilized tio 2 and photocatalytic activity

Abstract

In this present work, compound parabolic collector (CPC) combined with tubular reactors was designed to accept both directly incident and reflected light. The light collecting of CPC reflecter was analysed via light reflection modeling. Titanium isopropoxide was used as a precursor to prepare immobilized titanium dioxide on the borosilicate beads which was used as supporter. The coated beads were prepared via dip coating technique. The photocatalytic activity of immobilized TiO 2 was performed to decolorize the Rhodamine B dye solution under solar irradiation. UV-Vis spectrophotometer was used to characterize the degradation of rhodamine B dye solution and to analyse the photocatalytic performance. The analysis of reflecting on CPC reflector indicates that all incidents are reflected to reactor tube according to the defined concentration ratio as equal one. The photodegradation of rhodamine B dye solution under solar irradiation is clearly observed by over 90% in presence of immobilized TiO 2 on glass beads.
