- Holmium oxide nanostructures were synthesized by a facile precipitation route.
- Triethylenetetramine as a novel precipitant was applied.
- The influence of different capping agents and photocatalytic behavior of holmium oxide was investigated.
- The photocatalytic performance of as-obtained products was examined by applying methyl violet.
Holmium oxide nanostructures were prepared through a facile precipitation way applying triethylenetetramine as a novel precipitant and Ho(NO3)3·6H2O as a holmium precursor. The effect of different capping agents on the size, shape and photocatalytic behavior of holmium oxide was studied. It was found that the type of capping agent has an effective role in shape, size and photocatalytic behavior control. The as-produced holmium oxide has been analyzed with applying EDX, FESEM, DR-UV-vis, TEM, XRD and FT-IR. The photocatalytic performances of as-obtained holmium oxide samples have been compared in the degradation of methyl violet pollutant under UV illumination.
