“…However, recent developments in the area of electroless (e-less) deposition show promising results. They demonstrate that UPD-like monolayers can be synthesized on various catalytically relevant substrates using an e-less deposition with simple experimental routine and solution chemistry. − Several reports indicate that the e-less Pb ML (Pb ML e‑less ) deposition is of particular interest. − It occurs on substrates that do exhibit the Pb UPD phenomenon, and it can be used to modify catalytically active substrates (noble metals), improving their activity for particular reactions. , The Pb ML e‑less can also replace the UPD ML in the SLRR reaction, enabling formation of the catalyst ML on substrates with nonconductive support. In this case, the full deposition cycle requires consecutive immersion of the substrate in the solution for the Pb ML e‑less deposition (first step) and then in the solution for the SLRR, that is, catalyst deposition (second step).…”
