- •
Lead modified 111-Pt NPs display one of the highest current density values reported for FAOR at 0.5 V in 0.1 M HCOOH solution.
- •
Lead adatom presents a combined third body and bifunctional catalytic effect as modifier on Pt NPs.
- •
High catalyst stability is displayed at maximum lead coverage.
- •
SECM emerges as a suitable and fast tool to perform preliminary tests of electrocatalytic activity.
