An Easy-Made, Economical and Efficient Carbon-Doped Amorphous TiO2 Photocatalyst Obtained by Microwave Assisted Synthesis for the Degradation of Rhodamine B

Abstract: The search for novel materials and the development of improved processes for water purification have attracted the interest of researchers worldwide and the use of titanium dioxide in photocatalytic processes for the degradation of organic pollutants contained in water has been one of the benchmarks. Compared to crystalline titanium dioxide (cTiO2), the amorphous material has the advantages of having a higher adsorption capacity and being easier to dope with metal and non-metal elements. In this work, we take … Show more

“…The mechanism was inferred as follows: C element is merged in the TiO2 lattice, leading to a decrease for the optical bandgap of oxide crystal. TiO2 can constitute soft interfaces with different lattice parameters, and its optical quality does not rely on orientations owing to its isotropic nature [16,17]. These results confirmed the doping of C in TiO2 as well as the scalable generation of PCT photocatalyst.…”

“…It should be mentioned that about 85% of RhB was adsorbed on N/TiO 2− x during 30 min of stirring in the dark, since both oxygen vacancies and surface adsorbed F − contribute to this process. 39 In order to prove that the adsorbed RhB was degraded completely, FTIR test was conducted on N/TiO 2− x after 30 min adsorption in the dark and another 30 min visible light illumination. From Fig.…”

“…In the FT-IR spectra of the Au/TiO 2 /WO 3 -NWH-TA after the photocatalytic removal of MO (Figure S18c), the following absorption bands were observed: at ≈3400 cm -1 , assigned to the O-H stretching vibration [59] (due to the presence of TiO 2 and WO 3 ); at 1636 cm -1 , attributed to the H-O-H bending vibration of the water adsorbed on the photocatalyst surface; at 1402 cm -1 , due to the O-H in-plane bending on the TiO 2 surface [64]; at 1129 cm -1 , assigned to the Ti-OH stretching vibration [65]; at 827 cm -1 , due to the O-W-O stretching vibration; and at 650 and 515 cm -1 , assigned to the Ti-O-Ti and O-Ti-O stretching vibrations, respectively [56]. After each reusability cycle, the FT-IR spectra of the photocatalyst did not change significantly.…”
