A-Fe2O3 Nanorods for Degradation of Organic Pollutants Methyl Orange and Rhodamine B Dyes

Abstract

This work presents an important analysis and comparative study between two organic waste rhodamine B (RhB) and methyl orange (MO) dyes as pollutant models degeneration under sunlight. Hematite ([Formula: see text]-Fe2O3) nanorods were synthesized and deposited on glass substrates using an efficient and simple one-step hydrothermal method. The nanorods were characterized by XRD, FESEM, EDX, and UV–Vis equipment. The photodegeneration parameters of [Formula: see text]-Fe2O3 films were calculated by modeling the photodegradation of MO and RhB dyes as pollutants under sunlight irradiation for 150[Formula: see text]min. Results revealed that the degradation efficiency of [Formula: see text]-Fe2O3 films of MO and RhB dyes was 72.7% and 91.9%, respectively. The optimized photocatalyst degraded RhB more efficiently than the MO solution.
