- Pt single atoms on carbon nanotube were synthesized for Suzuki coupling reaction.
- The Pt single atoms showed a remarkably high activity and recyclability.
- The Pt single atoms were separated from the products by the simple filtering.
While a ligand-free condition for Suzuki coupling reaction is desirable to minimize the separation process of the final product, it adversely has affected a reaction kinetics. Herein, we report a promising candidate for active and recyclable heterogeneous catalyst for ligand-free Suzuki coupling: Pt single atoms on thiolated multi-walled nanotubes. They demonstrated a complete conversion (>99%) in the ligand-free condition for 24Â h, while conventional Pd or Pt complex catalysts showed just below 5% conversion. Also, they could be completely recollected by a simple filtering process and be recycled showing 82% yield retention after 12 cycles.
