Description 618-626
Herein, we report the fabrication of Ag metal loading on Zr-doped-N-TiO2 (AgZrT) nanocomposites (NCs) via
microwave-assisted impregnation reduction method. The main objective of the work is to study the effect of Ag loading on
structural, chemical and photoactivity of Zr-doped-N-TiO2(ZrT). The obtained NCs were characterized using XRD,
HRTEM, EDS, XPS etc. Obtained AgZrT NCs showed the existence of metastable anatase phase with an average crystallite
size of about 10 nm supported by HRTEM. The presence of Ti, Zr and Ag is confirmed by EDS while the metallic state of
Ag and oxidation state of Ti and Zr (+4) is confirmed by using XPS. The Ag loading effect on photoactivity of ZrT NPs was
studied under UV and direct sunlight using model dye Methyl Orange (MO). The positive impact of Ag metal loading is
supported by the enhanced photoactivity of ZrT. The degradation kinetics for MO and its plausible mechanism under
sunlight is proposed.
