Dyes released from textile and dyeing industries can distress the environment and becomes a threat to human health. In this study the photocatalytic efficiency of cerium (Ce) doped ZnO photocatalyst to remove azo-dye is highlighted. Different concentrations of Ce (0.2 0.4 0.6 0.8 and 1.0 mol ) were doped into ZnO and the as-prepared powder was characterized by using X-ray diffraction analysis (XRD) Fourier transforms infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). Photodegradation of 10 mg/l of methylene blue (MB) dye solution has been conducted under UV-C (254 nm) irradiation up to 180 minutes using 0.5 to 2.5 g/L of Ce doped ZnO powder. The findings revealed that photodegradation of MB increased with increasing Ce doping concentration and the addition of photocatalyst loads up to 2.0 g/L. Photocatalyst comprising 1 mol Ce doped ZnO performed the highest photocatalytic activity with the efficiency of 94.24.

Abstract

Dyes released from textile and dyeing industries can distress the environment and becomes a threat to human health. In this study the photocatalytic efficiency of cerium (Ce) doped ZnO photocatalyst to remove azo-dye is highlighted. Different concentrations of Ce (0.2 0.4 0.6 0.8 and 1.0 mol ) were doped into ZnO and the as-prepared powder was characterized by using X-ray diffraction analysis (XRD) Fourier transforms infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). Photodegradation of 10 mg/l of methylene blue (MB) dye solution has been conducted under UV-C (254 nm) irradiation up to 180 minutes using 0.5 to 2.5 g/L of Ce doped ZnO powder. The findings revealed that photodegradation of MB increased with increasing Ce doping concentration and the addition of photocatalyst loads up to 2.0 g/L. Photocatalyst comprising 1 mol Ce doped ZnO performed the highest photocatalytic activity with the efficiency of 94.24.
