Synthesis of Co-doped WO3 Nanoparticles

Check if the same lab product or an alternative is used in the 5 most similar protocols

Co doped WO₃ nanoparticles were synthesized using the microwave-assisted solution combustion method. Tungsten powder with 99.99 % purity (Sigma-Aldrich), and Cobalt nitrate hexahydrate (Co (NO₃)₂.6H₂O (Sigma-Aldrich) with 98 % purity, were used as the precursors. 3g of Tungsten powder was dissolved in 50 ml of 37 % H₂O₂. Then, 0.2g of Cobalt nitrate salt was added to the solution and it was stirred until the salt was completely dissolved. 1.5 g of citric acid was added as combustion fuel. To evaporate the water of the solution and form a gel, the obtained solution was placed on a heater stirrer for several minutes. Subsequently, the resulting gel was placed under the microwave irradiation at a power of 900 W to combust and produce the dry foam (Fig. 1). All the materials used in this process were of high purity materials and were purchased from Merck and Sigma-Aldrich.Fig. 1

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.
