Pt/Cu single-atom alloys as coke-resistant catalysts for efficient C–H activation

The recent availability of shale gas has led to a renewed interest in C–H bond activation as the first step towards the synthesis of fuels and fine chemicals.

In the study, published by Nature Chemistry, researchers, including TYC members Prof. Angelos Michaelides and Dr. Michail Stamatakis conducted catalytic reaction tests on methyl groups, methane, and butane using copper surfaces doped with isolated platinum atoms. 

The team found that compared with pure copper, the bimetallic catalysts avoid coking and lower the C-H activation temperature by 100°C or more depending on the reaction.
