Platinum Single Atoms on Carbon Nanotubes as Efficient Catalyst for Hydroalkoxylation

We report a facile synthesis of Pt single atoms on thiolated carbon nanotubes. To obtain Pt single atoms, it is crucial to treat thiol groups on carbon nanotubes. Pt single atoms on carbon nanotubes were used efficient catalyst for hydroalkoxylation of 3‐buten‐1‐ol or 4‐penten‐1‐ol. Hydroalkoxylation represents an atom‐economic route to construct four or five‐ membered cyclic ethers through intramolecular addition of hydroxyl group. This catalyst exhibited higher catalytic activity than Pt complex and Pt nanoparticles on carbon nanotubes.
