The Sabatier Principle was formulated about 100 Years ago. Explaining a lot of facts it helps to find possible catalysts excluding a lot of systems with very strong or very weak interactions between catalysts and reaction components . However, the remaining pool of catalytic systems is huge enough to guarantee a lot of necessary hard work to find a good catalyst. The Sabatier Principle is formulating an necessary but not sufficient condition, a good catalyst has to met.

Could anyone give me an example of a real catalyst developed by help of the Sabatier Principle? I cannot, sorry.
This Principle is only one of many aspects You should have in mind developing catalysts.To predict the activity of heterogeneous catalysts for a given reaction, above all You need a lot of experience for the given catalytic system.
