Photocatalytic degradation of malachite green dye over naked niobium oxide as a photocatalyst

الملخص EN

This study is one application of Advanced Oxidation Process (AOPs) that is using Naked Niobium Oxide (Nb2O5) as a photocatalyst to degrade the industrial Malachite Green dye.

Malachite Green is used in many industries such as leather, silk, paper, plastic and others.

This research involved Study different factors of photodegradation [weight of catalyst (0.03 – 0.3) g, initial concentration of dye (5 – 15) ppm, temperature (5 – 25) °C, light intensity (2.3 – 3.5) mW / cm2 , pH (2 – 8), adding of hydrogen peroxide (0.5 – 2) mL and type of gas (air, N2)].
