Abstract

Tungsten oxide (WO3) is a wideband gap n-type, transition metal oxide semiconductor. It is a high refractive index trioxide compound that exhibits good corrosion resistance in solutions with strong acids. It also provides high-performance characteristics such as optical modulation, great durability, photochromic behaviors, and coloration efficiency. With such superior chemical and physical properties, tungsten oxide becomes suitable for a wide range of applications such as photocatalysis, sensors, and super-capacitance. According to previous studies, compositing other materials is a suitable method for electron-hole pair separation. This work reviews and illustrated the improved properties of WO3 by combining with metals in the form of core-shell nanocomposites with metal cores and oxide shells have emerged as attractive materials with high stability and remarkable synergy between their components, which enable a combination of several attractive properties in the same material.
