The photocatalytic dye degradation efficiency of the prepared nanoparticles against MB and MV was found to be 92% and 85% , respectively. Photocurrent measurement confirms the charge carrier generation during exposure to visible light. A density functional theory (DFT) calculation was performed to ...
Graphitic carbon nitride (g–C3N4), an organic photocatalyst was reported to have beneficial properties to be used in wastewater treatment applications. However, g–C3N4, in its bulk form was found to have poor photocatalytic degradation efficiency due to its inherent limitations such as poor specifi...
(h+, O2−and·OH). We believe that the novel three-way Ag2O/AgBr–CeO2catalyst could have great potential in the field of energy and environmental protection. This work could provide a different Z-scheme heterojunction system to construct ternary catalysts improving the degradation efficiency. ...
The results from the absorbance of dye degradation reveal that there is no shift of absorption peak of dye. Obviously, the major absorption peak of methylene blue, Malachite green, and Congo red is located at 668, 620, and 490 nm, which clearly decreases in intensity with increasing ...
The synthesized photocatalyst was characterized by X-ray diffraction, Fourier transform infrared, X-ray photoelectron spectroscopy, and UV–Vis diffuse reflectance spectroscopies, scanning electron microscopy and transmission electron microscopy, and subsequently utilized for photocatalytic dye degradation and ...
MH2O]. The method of photocatalytically degrading the methyl orange-methylene blue mixture dye by using the zinc-tin binary hydrotalcite has the advantages of mild reaction conditions, high degradation efficiency and obvious effect, and the catalytic degradation product can be easily recycled.倪哲明...
On different pH value of the dye, the percentage degradation of the dye will decrease in both acidic and alkaline condition. Keywords: photocatalytic degradation; Congo red dye; TiO 2 ; catalyst; solar; UV lamp 展开 DOI: 10.4314/JFAS.V10I1S.62 年份: 2018 ...

Herein, we have mainly investigated its activity and stability under indoor weak light for the degradation of dye pollutants. It is amazing that under indoor weak light irradiation, rhodamine B (RhB) can be completely degraded by Ag3PO4 polypods after 36 h, but only 18% of RhB by N-...
In this study, the photocatalytic degradation of commercial azo dye (Remazol Red 133) in the presence of titanium dioxide (TiO 2 ) suspensions as photocatalyst was investigated. The effect of various operational parameters, such as pH of dye solution and catalyst concentration on the photocatalytic...
