Understanding how palladium inhibits CO poisoning is important for rational design of enhanced catalysts. Here the authors show high formate coverage on the palladium-modified electrode inhibits poisoning during formic acid oxidation and the adsorption of CO precursor dictates the delayed poisoning during CO2 reduction.
