Introduction:

Electrochromic devices have gained significant attention in recent years due to their ability to change their optical properties in response to an applied electric field. These devices have potential applications in smart windows, displays, and energy storage systems. Among various electrochromic materials, tungsten trioxide (WO3) has been extensively studied due to its unique electrochromic properties. However, the development of efficient and cost-effective methods for the preparation of WO3-based electrochromic devices is still challenging.

In this work, we report a novel, simple, and low-cost method for the preparation of WO3-based electrochromic devices using sodium citrate-assisted chemical bath deposition (CBD). The use of sodium citrate as a complexing agent facilitates the deposition of WO3 onto a substrate, resulting in a uniform and smooth film. Moreover, this method allows for the incorporation of Prussian blue (PB) as a secondary component, which offers the dual functionality of electrochromism and energy storage.

The incorporation of PB into the WO3 matrix leads to the formation of a WO3-PB hybrid material, which exhibits excellent electrochromic properties. The electrochromic response of the WO3-PB hybrid material can be attributed to the reversible redox reaction of WO3 and PB, which leads to a change in the optical properties of the material. The energy storage capability of the WO3-PB hybrid material is attributed to the electrochemical activity of PB, which acts as a pseudo-capacitive material.

The aim of this work is to demonstrate the feasibility of sodium citrate-assisted CBD as a simple and low-cost method for the preparation of WO3-PB hybrid materials. The electrochromic and energy storage properties of the WO3-PB hybrid material are characterized using various techniques, including cyclic voltammetry, electrochromic spectroscopy, and energy storage measurements. The results of this work demonstrate the potential of WO3-PB hybrid materials for the development of efficient and cost-effective electrochromic and energy storage devices.

In summary, this work presents a simple and low-cost method for the preparation of WO3-PB hybrid materials using sodium citrate-assisted CBD. The electrochromic and energy storage properties of the WO3-PB hybrid material are characterized, demonstrating the potential of this material for the development of efficient and cost-effective electrochromic and energy storage devices
