Degradation Of Methyl Orange

Nano-TiO2 photocatalyst powders were prepared through the sol-gel method and supercritical fluid drying(SCFD). The TG-DTA、XRD、particle size distribution technique、SEM were used to characterize the hyperfine TiO2 particles.The lanthanum-doped TiO2 with different mass percentage of La3+ were compared with pure TiO2 when used as photocatalyst in degradation of methyl orange. The best catalytic activity was observed with 0.02(mol)%La-TiO2. Photocatalytic efficiency of the 0.02(mol)%La- TiO2 is improved by 30.79% comparing to pure TiO2.

Degradation Of Methyl Orange

Abstract. The present work focuses on the photo-catalytic degradation of methyl orange (MO) on Erbium trioxide nanoparticles Er2O3 NPs. In this study, Er2O3 nanoparticles were synthesized and fully characterized via various techniques including; XRD diffraction, UV-Vis spectroscopy and SEM techniques. The results revealed that, the photo-catalytic activity of the prepared Er2O3 NPs towards methyl orange (MB) photo-degradation was manifested. The optimum efficiency obtained was 16 %.

Degradation Of Methyl Orange

Nano-size Ag-N co-doped ZnO-CuO composites have been synthesized and tested for their photo-catalytic activity towards degradation of methyl orange in aqueous solution under visible as well as UV radiations. Crystal structure, surface functional groups, metallic composition and band structure of as-synthesized nano-material were investigated using XRD, FTIR, AAS and UV-Vis spectroscopic techniques, respectively. Ag-N co-doped ZnO-CuO photocatalyst showed higher photo-catalytic activity than Ag- or N-doped and undoped composite photocatalysts. The observed highest activity of Ag-N co-doped ZnO-CuO among the studied photo-catalysts, is attributed to the cumulative effects of lowering of band-gap energy and decrease of recombination rate of photo-generated electrons and holes owing to doped N and Ag, respectively. Effects of photo-catalyst load, solution pH and substrate initial concentration on the degradation of methyl orange have also been studied.
