The sabatier principle
WebbThe Sabatier principle states that the interaction between a catalytic surface and its substrate needs to be finely tuned for the catalyst to be effective – if the interaction is too strong then the product will get stuck, too weak and the reactants dissociate before the catalytic pathway can proceed.

Webb10 nov. 2024 · According to the Sabatier principle, the adsorption of ORR intermediates ( i.e., O 2 *, OOH*, O* and OH*) on the active site should be neither too strong nor too weak. 92 Unfortunately, like benchmark Pt, the adsorption of ORR intermediates on the Fe–N x sites is still too strong, which seriously limits their desorption and then the ORR kinetics, …
