Exploring the lattice oxygen participation in selective oxidation catalysis
Quick fact
Using isotopic labeling, such as 18O2, scientists can track the incorporation of lattice oxygen from a metal oxide catalyst into the oxidation product, confirming that the catalyst is not merely a spectator but an active participant.
Why this is interesting
When a catalyst helps a reaction, we often imagine it simply providing a surface where molecules meet. But what if the catalyst itself donates a piece of its own structure to the product—and then repairs itself?
