Carbon modified anatase TiO2 for the rapid photo degradation of methylene blue: A comparative study

Biological and photocatalytic treatment at pilot plant scale of synthetic coloured wastewater produced in university teaching laboratories

“…Rutile phase signals presented less intensity and 110 and 211 planes were observed. Results are in line with those reported by Sigma-Aldrich (Muniandy et al, 2016). The presence of those two phases allows for a more efficient dye oxidation, because the presence of both represents a higher redox potential, which is achieved by the transfer of electrons from the conduction band of the anatase phase to the conduction band of the rutile phase (Gómez, 2018).…”

“…Sigma-Aldrich and Degussa P25 TiO 2 are semiconductor oxides with high percent purity (99.5% Sigma-Aldrich and 94% Degussa P25). Both have been used in various photocatalytic studies (Dnyaneshwar et al, 2017;Muniandy et al, 2016). In relation to TiO 2 USP from "Quimicos de la 13" and "Quimicos Campota Ltda", its purity was 90%.…”

Synthesis of lignin based composites of TiO2 for potential application as radical scavengers in sunscreen formulation

“…The XRD diffractograms in Fig. 8 reveal that both composites had similar XRD patterns to that of pure anatase TiO 2 [22]. The diffraction peaks at 2θ = 25.4°, 37.9°, 48.1°, 53.9°, 55.1°, 62.7°, 68.8°, 70.4°, 75.1° and 82.7° can be indexed to (101), (004), (200), (105), (211), (204), (115), (220), (215) and (224) crystal planes of anatase TiO 2 , respectively.…”

Palladium‐Modified TiO2/MWCNTs for Efficient Carbon Capture and Photocatalytic Reduction of Nitro‐aromatic Derivatives

“…Then water was added till neutrality. The functionalized MWCNT (f‐MWCNT) was filtered out, and dried at 80 °C for 12 h [25] . The as‐synthesized f‐MWCNT and sodium dodecyl benzene sulfonate (SDBS) as a dispersing agent were mixed in equal mass ratio 1 : 1=f‐MWCNT:SDBS) and added to absolute ethanol (25 mL) and subjected to ultrasound irradiation for 1 h [labeled by mixture (A)].…”
