Hydrothermal Synthesis of W-V-Mo Catalysts

Check if the same lab product or an alternative is used in the 5 most similar protocols
The W-V-Mo catalysts, were prepared hydrothermally from gels obtained from the aqueous solution of corresponding salts: ammonium metatungstate hydrate (≥85 wt% WO3 basis, Sigma-Aldrich), vanadium (IV) oxide sulfate hydrate (≥99.99%, Sigma-Aldrich) and ammonium heptamolybdate tetrahydrate (GR for analysis, MERCK). The hydrothermal synthesis was carried out at 175°C for 48 h; then the solid was washed and dried at 100°C overnight. We refer to the dried solid as "catalyst precursor". Lastly, the catalyst precursor was heattreated in N2 at 600°C for 2 h. Only for selected analysis, the catalyst precursor was heat-treated in N2 at 800°C for 2h. In the latter case, specific mention of the not-conventional heattreatment is reported.

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.
