The “ten electron rule” provides guidance for the design of single-atom alloy catalysts for targeted chemical reactions. This rule states that the total number of valence electrons in the catalyst should be close to ten for optimal activity. The rule is based on the idea that the electronic structure of the catalyst is responsible for its catalytic properties. By controlling the electronic structure of the catalyst, it is possible to tune its activity and selectivity for specific reactions.

Catalyst Design Rule: The Ten Electron Rule for Single-Atom Alloy Catalysts

Catalysts play a crucial role in countless chemical reactions, speeding them up and making them more efficient. Single-atom alloy catalysts, a relatively new type of catalyst, have shown remarkable efficiency in accelerating chemical reactions. However, traditional models have struggled to explain their workings.

A collaborative effort by researchers from four universities has resulted in the discovery of a simple rule that guides the design of single-atom alloy catalysts for specific chemical reactions. This “ten electron rule” simplifies the identification of promising catalysts, eliminating the need for extensive trial-and-error experiments or computationally demanding computer simulations.

Understanding Single-Atom Alloy Catalysts

Single-atom alloy catalysts are composed of two metals: a few atoms of a reactive metal (the dopant) dispersed in an inert metal (such as copper, silver, or gold). This technology has revolutionized the field of catalysis due to its exceptional efficiency in accelerating chemical reactions.

The Ten Electron Rule: A Guiding Principle for Single-Atom Alloy Catalyst Design

The “ten electron rule” provides a straightforward method for designing single-atom alloy catalysts. It states that chemicals bind most strongly to these catalysts when the dopant is surrounded by ten electrons.
