چکیده
Al2O3 doped Mn3O4 nanomaterial was synthesized by low-temperature stirring method and applied as a catalyst for the degradation of organic pollutants under solar light for prospective environmental applications. The morphological and physiochemical structure of the synthesized solar photocatalyst was investigated by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy-dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FT-IR), and X-ray photoelectron spectroscopy (XPS). FESEM showed a mixture of nanowires and aggregated nanoparticles. This Al2O3 doped Mn3O4 nanomaterial exhibited high solar photocatalytic degradation in a short time when applied to brilliant cresyl blue (BCB). Thus, the synthesized nanoparticles can be used as an efficient solar photocatalyst for the degradation of BCB.
