Synthesis and Oxygen Storage Capability of CeO2 Powders for Enhanced Photocatalytic Degradation of Acid Orange 7

نویسندگان

چکیده

Acid Orange 7 (AO7) is one of the most common azo dyes; however, its strong bond makes them difficult to biologically degrade. We sought degrade AO7 dye using CeO2 as a promising alternative photocatalyst. powders were synthesized with monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA) precipitant by solvothermal process combined calcination in air. Compared oxygen storage capability Blank-CeO2 (0.186 mmol O2/g), that MEA-CeO2 presence MEA increased 21.0%, while DEA-CeO2 TEA-CeO2 DEA TEA precipitants decreased. Importantly, such exhibited highest photocatalytic activity than Blank-, DEA-, degradation under simulated sunlight illumination, removal rate could reach 98.3% within 100 min.

Photocatalytic Degradation of Methyl Orange by CeO2 and Fe–doped CeO2 Films under Visible Light Irradiation

Undoped CeO2 and 0.50-5.00 mol% Fe-doped CeO2 nanoparticles were prepared by a homogeneous precipitation combined with homogeneous/impreganation method, and applied as photocatalyst films prepared by a doctor blade technique. The superior photocatalytic performances of the Fe-doped CeO2 films, compared with undoped CeO2 films, was ascribed mainly to a decrease in band gap energy and an increase...

Synthesis, characterization and photocatalytic activity of CeO2-SBA-15

Mesoporous photocatalysts of CeO2/SBA-15 are prepared by two methods of direct synthesis as solvent-usage and solvent-free methods. In solvent-usage method, CeO2/SBA-15 is synthesized in acidic media. While, in solvent-free method, CeO2/SBA-15, has been prepared through the novel path of directly grind cerium salt into the as-prepared samples of SBA-15 occluded ...
