Abstract

A rate-aligned electrocatalyst is reported that provides tunable access to a range of synthesis gas compositions as a function of potential. These electrocatalysts comprise a Au CO-generating component and a Co, Fe, or Ni H 2 -generating component. The orthogonal integration of these two materials enhances the ability to tune syngas ratio, such that a wide range of desirable syngas compositions are accessed over a narrow potential range, all at high geometric current densities.
