Efficacious separation of electron–hole pairs in CeO2-Al2O3 nanoparticles embedded GO heterojunction for robust visible-light driven dye degradation

Highly Efficient Degradation of Polyacrylamide by an Fe-Doped Ce0.75Zr0.25O2 Solid Solution/CF Composite Cathode in a Heterogeneous Electro-Fenton Process

“…For comparison, CeO 2 , ZrO 2 , and Fe 3 O 4 were also discerned by FT-IR spectroscopy. Upon comparison of FT-IR spectra before and after Fe-Ce 0.75 Zr 0.25 O 2 loading on CF, the absorption peaks at 586.07 cm –1 (Zr–O–Zr), 529.09 cm –1 (Fe–O), 510.02 cm –1 (Ce–O), and 410.83 cm –1 (Zr–O) were all in the infrared spectrum of Fe-Ce 0.75 Zr 0.25 O 2 /CF. − While the absorption peak strength of the carbon–carbon triple bond or cumulative double bond functional group was weakened, the stretching vibration absorption peaks of the C–O bond at 1082 and 1022.81 cm –1 were also presented for CF after loading Fe-Ce 0.75 Zr 0.25 O 2 . Results indicated that the Fe-Ce 0.75 Zr 0.25 O 2 catalyst had been successfully loaded on the surface of CF.…”

A Novel CeO2/Cu2O/CuO Nanocomposite Designed from a CeAlCu Glass Precursor as an Excellent Dual Function Catalyst in Dye Wastewater Remediation

“…Cu 2 O, [11] Cu, [45] CuO, [46] Cu/Cu 2 O/CuO, [32] CeO 2 /Cu 2 O, [19] CeO 2 /CuO, [35] and CeO 2 /Al 2 O 3 [47] are common photocatalysts, so we investigated the photocatalytic performance of the sample C1 and commercial pure samples for the degradation of MB and RhB in aqueous solution under visible light irradiation with the addition of H 2 O 2 . The sample C1 could not degrade these dyes in the dark (Figure 3(e)).…”

Novel bimetallic MOF derived N-doped carbon supported Ru nanoparticles for efficient reduction of nitro aromatic compounds and rhodamine B

“…50 Nevertheless, they are very structurally robust and difficult to biodegrade directly. 51,52 Currently, owing to its high conversion efficiency, catalytic reduction is widely regarded as the most promising method to remove these contaminants from industrial waste water. 48,53 However, the activity and stability of the catalyst greatly determine the catalytic efficiency.…”
