Mapping proton and carbon dioxide electrocatalytic reductions at a Rh complex by <i>in situ</i> spectroelectrochemical NMR.

ABSTRACT: Detailed molecular level understanding of organometallic electrocatalytic systems is required to fully exploit their technological potential to store, distribute, and utilise renewable energy in chemical form. However, in situ methods providing high resolution information on the structure and reactivity of transient intermediates remain challenging due to incompatible requirements for standard electrochemical and spectroscopic cell designs. Here, we demonstrate the use of spectroelectrochemical nuclear magnetic resonance (SEC-NMR) to enable operando characterisation of molecular species during organometallic electrocatalysis. The electroreduction of a prototypical molecular rhodium(+i) diphosphine complex was studied under aprotic conditions and in the presence of H₂
