Properties of polymeric surfactant mediated ZnWO4 nanoparticles for photocatalytic application

Abstract

ZnWO4 has received a great deal of attention among the researchers, because of its multi-dimensional characteristics in the field of sensors, optoelectronics and photocatalytic devices. In this work, we report on the synthesis of ZnWO4 nanoparticles using co-precipitation technique with polymeric surfactant. This study aimed to investigate the effect of increasing concentration of surfactant on the morphology, particle size and crystal structure of the synthesized catalyst. The synthesized sample was investigated by XRD, UV-Vis, FT-IR and SEM-EDX to identify its various properties. The XRD analysis confirmed the formation of monoclinic structure of ZnWO4. The EDX study proved the purity of synthesized product. The characteristic molecular vibrational information of ZnWO4 product was obtained through FT-IR measurement.
