The reconstruction of Cu electrocatalysts during CO2 reduction is an impediment to the stability of this technology, yet a clear picture of the species involved in this process remains elusive. Here, the authors demonstrate the presence of transient solution-based Cu(I) species and theoretically predict complexes with CO and oxalate as the likely candidates.
