Catalyst Preparation Methods and H2-TPD

Example 3

Two samples of catalysts have been prepared, one by co-precipitation (CP) and the other one by deposition impregnation (DI). H₂-TPD was performed at 5.0 MPa (FIG. 6) resulting in a temperature of around 313 K for the material prepared by DI versus 293 K for the material prepared by CP.

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.
