Wo3 nanoparticles

Manufactured by Merck Group

Sourced in United States

WO3 nanoparticles are a type of inorganic nanomaterial with a chemical composition of tungsten trioxide. They exhibit unique optical and electrochemical properties due to their small size and high surface area. The core function of WO3 nanoparticles is to serve as a versatile material for various applications, including electrochromic devices, photocatalysis, and gas sensing.

EGaIn, acetic acid (>99%), ammonium acetate powder (>99%), lead (II) acetate 3-hydrate, and WO₃ nanoparticles (≈100 nm) were purchased from Sigma Aldrich, USA. 0.1% (v/v) acetic acid solution was prepared by adding 50 μL acetic acid into 49.95 mL DI water. WO₃ suspension was prepared by mixing 50 to 200 mg WO₃ nanoparticles with 10 mL 0.1% acetic acid solution to yield concentrations of 5 to 20 mg mL⁻¹. Then the WO₃ suspension was kept in a sonication bath for 20 min to prevent agglomeration.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
