Abstract
A new way of preparing dysprosium titanate (Dy2Ti2O7) nanoparticles has been developed using the sol–gel auto-combustion route, with the aid of dysprosium nitrate, tetra-n-butyl titanate (TNBT) and tyrosine. Tyrosine plays role as fuel, capping agent, and reducing in the synthesis of Dy2Ti2O7 nanoparticles. The formation of pure crystallized Dy2Ti2O7 nanocrystals occurred when the precursor was heat-treated at 800 °C in air for 2 h. The structural, morphological and optical properties of as-obtained products were characterized by techniques such as XRD, EDS, SEM, and UV–visible. The magnetic properties of as-prepared dysprosium titanate nanoparticles were also investigated with vibrating sample magnetometer. Furthermore, the photocatalytic properties of as-synthesized Dy2Ti2O7 were evaluated by degradation of methyl orange as water contaminant.
