Fast degradation of methylene blue with electrospun hierarchical α-Fe2O3 nanostructured fibers

Heterogeneous photo-Fenton degradation of organics using highly efficient Cu-doped LaFeO3 under visible light

“…As is well known, inorganic ion such as chloride (Cl -) is commonly present in the wastewater originated from dyestuff and textile industries; thus, its effect on photodegradation of MO cannot be neglected. Taking account of the negligible effect of Na + [74], our results revealed that Clappeared to inhibit the MO removal by using LFO-15Cu. In the presence of 0.01 M Cl -, only 62.8% MO (k = 0.0170 /min) was removed, which was much lower than that (92.9%; k = 0.0468 /min) when no Clwas added in the dye-containing solution.…”

Photobiological synthesis of noble metal nanoparticles using Hydrocotyle asiatica and application as catalyst for the photodegradation of cationic dyes

“…The color of MB solutions becomes less intense (hypsochromic effect) when auxochromic groups (methyl or methylamine) are removed. For dyes containing auxochromic alkylamine groups, N-dealkylation plays an important role in photocatalytic degradation [68]. No new peaks for intermediates appeared during the degradation of both MG and MB and almost nil COD value after the reaction indicates the complete degradation of dyes in sunlight.…”

Hollow α-Fe2O3 nanofibres for solar water oxidation: improving the photoelectrochemical performance by formation of α-Fe2O3/ITO-composite photoanodes

“…36 Further, electrospun a-Fe 2 O 3 bres were photocatalytically investigated in terms of degradation of methylene blue. 37 Li et al 38 reported on the photoelectrochemical characterisation of electrospun La-doped a-Fe 2 O 3 nanotubes observing increased conductivity and light absorption due to the effect of doping.…”
