Abstract

In this paper, we report the synthesis of tellurium (Te) doped ZnO nanocrystals for photocatalytic applications. X-ray diffraction, Fourier transforms infrared, photoluminescence and field emission scanning electron microscope are the techniques employed to characterize the properties of the prepared products. The photocatalytic activities of the undoped and doped ZnO are analyzed by the degradation of brilliant green (BG). The results of the degradation reveal that ZnO doped with Te has higher photocatalytic performance than undoped ZnO.

Highlights

In the modern scientific era the materials in the nanoscale have gained more attention than their bulk form owing to their peculiar physical and chemical properties [1]

Summary

Introduction

In the modern scientific era the materials in the nanoscale have gained more attention than their bulk form owing to their peculiar physical and chemical properties [1]. Brilliant green (BG) creates an impact on its enriched outreaching to the environment through effluent of textiles and paint industries [2,3,4,5,6,7,8,9]. Doping that does essential incorporation of ions of particular elements into the host material to tailor its properties is a widely accepted technique in the semiconductor industry. The morphology control through doping is another major task as the size and shape can influence various properties of the prepared products. We have attempted to tailor the photocatalytic properties of ZnO by incorporating Te in the lattices of Zn2+. The prepared products are analysed for their structural, optical, morphological, and photocatalytic properties
