Carbon nanodots (CNDs) have been synthesised using a simple and cheap pyrolysis method. ThePd/CNDs electrocatalyst was synthesised by the in-situ reduction method. The calculated particle sizeswere found to be 6.0 nm and 0.974 nm for CNDs and Pd nanoparticles, respectively. The reactionkinetics of the Pd/CNDs was found to have an onset potential of -0.111 V, which is 0.052 V lower thanthat of Pd/C. CNDs are good electrocatalysts support, as supported by durability and stability studies.The electrocatalyst showed improved durability and stability when CNDs were used as the supportmaterial for the Pd nanoparticles.
