Review on the Synthesis Methods of Nano-Tungsten Oxide Dihydrate Colloid

Tungsten being a transition element, forms oxide compounds of various oxidation states that enables it to form nanocolloids tungsten dihydrate. Multiple methods have been used in recent years synthesize nano dihydrate, including sol-gel synthesis, electrochemical deposition, hydrothermal synthesis and anodization. However, universally accepted method for this material is not offered. The most appropriate its corresponding processing parameters the dihydrate colloids were presented present study. objective study was investigate effect parameters, i.e. applied voltage, temperature anodizing duration on particle size nanocolloids. It found anodization easiest, efficient, cost-effective colloidal solution Conducting at room voltage 50 V 60 minutes yields product with 40 – nm, which can be wide array applications. This paper also highlights research gaps future work gives recommendations extend particularly industrial application oxide.
