Abstract

Titania has been one of the promising alternatives in treating environmental pollution issues and was considered in various applications due to its flexible behaviour. Many studies have been conducted to test its phasechanging properties and adaptive ability such as calcination process, and metal and nonmetal modification using mono-doped or co-doped elements. In the present study, the photocatalyst was developed from embedment with activated carbon (AC) followed by co-doping of Cu2+ and Fe3+ metal ions. The photocatalyst was characterized by XRD, BET and FESEM. The synthesized photocatalyst was tested in the photocatalytic degradation system for ionic liquid (IL) at the optimized parameters which includes solution pH = 6, photocatalyst = 1 g L-1 and H2O2 = 0.75 ml L-1. The co-doped product exhibited a smaller crystalline sizes as compared to bare TiO2. In addition, copper and iron dopants are well dispersed into the TiO2 lattice as no additional phases were detected. Maximum degradation of 77% of 0.11mM IL was recorded in the Cu:Fe-TiO2/AC system after 240 min of visible light irradiation. The system�s efficiency in terms of tested photocatalysts is in the order of P25 < TiO2 < TiO2/AC < Cu:Fe-TiO2/AC, respectively. © 2021, Islamic Azad University. All rights reserved.
