Enhancing the performance of interfacial electrocatalysts by engineering the monomer composition and sequence of metallo-oligomer monolayers

Abstract

Hetero-metallo-oligomer monolayers should be superior to their monomers for interfacial electrocatalysis. Here, we present a strategy to optimize and enhance the performance of interfacial electrocatalysts by engineering the composition and sequence of distinct metal complexes. The catalytic current density of the alternating hetero-heptamer monolayers is 10 and 2.4 times higher than those of the self-assembled and homo-heptamer monolayers, respectively.
