Characterisation of Industrial Catalyst

All industrial catalysts must have the following properties :

  • It should adsorb one or more reactants sufficiently strongly.
  • The adsorption must not be strong to prevent desorption of products.

For example :

Silver (Ag) — Doesn’t have strong adsorption properties.

Tungsten (W) — Adsorbs very strongly so desorption will not occur. So, Ag and W are not considered as good catalyst but Pt and Ni fulfills both the conditions to become good catalyst.

The two most important considerations for a solid to become good catalyst are–

  • High activity.
  • Long term stability or durability.

Thanks for reading. 🙂
