Pt-Sn/CeO2 Catalyst Synthesis

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

Example 24

The catalyst included 1 wt % of Pt and 3 wt % of Sn supported on CeO2, based on the weight of the CeO2. The CeO2 support was made by calcining cerium (III) nitrate hexahydrate (Sigma-Aldrich 202991). The catalyst was made by incipient wetness impregnation of 3 g of CeO2 with 0.788 g of 8 wt % chloroplatinic acid in water (Sigma Aldrich, 262587) and 0.266 g of tin (IV) chloride pentahydrate (Acros Organics 22369), followed by drying and calcination at 800° C. for 12 h. The data in Table 9 shows that the catalyst was stable over 42 cycles.

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.
