Length tunable penta-twinned palladium nanorods: seedless synthesis and electrooxidation of formic acid

Abstract

Palladium nanorods with controlled lengths from 100 to 500 nm and a fixed width of 20 nm were synthesized for the first time by a seedless approach. These rods show higher peak current densities than Pd cubes for formic acid oxidation and the catalytic activity decreases with increasing rod length.
