Formation of nano-tungsten oxide dihydrate colloids via anodization method

The present project focuses on the study of the effect of processing parameters on the particle size, conductivity and antibacterial property of the tungsten oxide dihydrate nanocolloids.

Tungsten Oxide (WO3) is a metal oxide semiconductor which possesses tunable bandgap energy ranging from 2.5 – 2.8 eV with potential usage in variety of applications such as photosensors and smart windows. Tailoring the nanostructures of tungsten oxide into different morphologies alters the properties of this material which widens the radius of its application and makes WO3 a fascinating element to examine. Tungsten being a transition element, forms oxide compounds of various oxidation states which enables it form nanocolloids of tungsten oxide dihydrate. There are multiple methods to synthesize nano tungsten oxide dihydrate such as Sol-Gel synthesis, Electrochemical Deposition, Hydrothermal synthesis and Anodization but as of now, a universally accepted synthesis method for this material is not offered. With this review paper, a universal method for the synthesis of nano tungsten oxide dihydrate colloids will be presented. The objective of the present study is to investigate the effect of processing parameters, i.e. applied voltage and anodizing duration on the particle size, conductivity and antibacterial property of the nanocolloids. This paper also highlights the research gaps for future work and gives recommendations to extend this study.
