文摘

Present work describes a facile approach to synthesize highly photocatalytically active holmium oxide (Ho₂O₃) nanostructured photocatalyst with the aid of [HoL(NO₃)₂]NO₃ (L = bis-(2-hydroxynaphthaldehyde)-1,2-ethandiamin), as novel holmium source and sodium dodecyl sulfate as capping agent. To investigate the influence of the capping agent dosage on the particle size and morphology of holmium oxide, several experiments were carried out. The structural, optical, magnetic and morphological characteristics of as-synthesized Ho₂O₃ nanostructures were analyzed by energy dispersive X-ray microanalysis, field emission scanning electron microscopy, UV–Vis diffuse reflectance spectroscopy, thermo-gravimetric analysis, X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, and vibrating sample magnetometer techniques. Moreover, the photocatalytic degradation of the erythrosine, eosin Y and methylene blue as water pollutants was carried out to evaluate the catalytic properties of as-obtained Ho₂O₃ nanostructures.
