Sabatier principleScaling relationDescriptorWe discuss three concepts that have made it possible to develop a quantitative understanding of trends in transition-metal catalysis: scaling relations, activity maps, and the d-band model. Scaling relations are correlations between surface bond energies of ...
Here, we describe how a simple experiment combined with results from density functional theory (DFT) can be used to introduce the Sabatier principle and its importance when designing new catalysts for the HER. We also describe the difference between reactivity and catalytic activity of solid ...
The Sabatier principle is the main theory that is used to understand the OER activity of electrocatalyst materials. The main active sites for OER are the surface metal cations (M). During the reaction, many reaction intermediates will form having an M-O bond. Sabatier's principle describes that...
All in all, in accordance with the Sabatier principle, a better performance of the hydrogen evolution reaction is conceivable for those values of the Gibbs free energy of hydrogen adsorption (ΔGH) that are closer to zero. This is attributable to the fact that even though the materials ...
Traditionally, the catalytic activity of a material can be described using the binding energy of species involved in the mechanism of the catalysed reaction. According to the Sabatier principle, species should bind neither too weakly nor too strongly to ensure optimal catalytic activity6, and the el...
This perspective article juxtaposes the different views of the optimum binding energy for the HER by means of the Sabatier principle, microkinetic considerations, DFT calculations, and experiments, and provides an outlook of potential future investigations by the combination of experiments with DFT aiming...

as a volcano-shaped plot—a graphical representation of the Sabatier principle that defines an effective catalytic surface to be neither too reactive nor too inert33, so that it both binds effectively to the reactants and readily releases the products of the reaction. The Sabatier principle has ...
Recently, the prediction based on the Sabatier principle has become a more powerful approach owing to the pioneering research by Nørskov et al. [96,125,147]. Instead of experimentally identifying the binding energy of a key intermediate, they developed the DFT methods to calculate the ...
