Porous TiO2 with large surface area is an efficient catalyst carrier for the recovery of wastewater containing an ultrahigh concentration of dye

摘要: The preparation of porous TiO2 as a carrier for the Fenton reaction is reported. Porous an excellent to load with elemental iron due large specific surface area and negative charge. was synthesized in form hierarchically silica monolith that used microreactor, block copolymer served template mesoporous forms. crystalline growing confined spaces maintained structure high crystallinity. our can reach 205 m2 g−1. zeta potential low −36.5 mV (pH 7). Elemental highly uniformly dispersed over channel via impregnation method catalyst reaction. In reaction, performed strong catalytic activity during degradation wastewater containing ultrahigh concentration aqueous dye, at 400 ppm. dye solution degraded 95% 30 min, could be reused many times.
