NANOSTRUCTURES OF N/ZNO FOR PHOTOELECTROCATALYSIS OF WATER IMPURITIES

摘要

In present investigation, we have synthesized various nanostructures of N-doped zinc oxide thin films by chemical spray pyrolysis technique using zinc acetate and N,N-Dimethylformamide (HCON(CH3)2 at 450 °C substrate temperature on to the amorphous and conducting [Fluorine doped tin oxide (FTO), 5-10 Ω/cm2] glass substrates in aqueous and non-aqueous media. The photochemical and photocatalytic oxidation of oxalic acid in a photoelectrocatalytic (PEC) degradation reactor, at room temperature, under sunlight illumination, coated with nanostructures of NZO photocatalysts were investigated. The extent of the degree of mineralization has been confirmed by measuring chemical oxygen demand (COD) and total organic carbon (TOC).
