To date, copper is
the only heterogeneous catalyst that has shown
a propensity to produce valuable hydrocarbons and alcohols, such as
ethylene and ethanol, from electrochemical CO<sub>2</sub> reduction
(CO<sub>2</sub>R). There are variety of factors that impact CO<sub>2</sub>R activity and selectivity, including the catalyst surface
structure, morphology, composition, the choice of electrolyte ions
and pH, and the electrochemical cell design. Many of these factors
are often intertwined, which can complicate catalyst discovery and
design efforts. Here we take a broad and historical view of these
different aspects and their complex interplay in CO<sub>2</sub>R catalysis
on Cu, with the purpose of providing new insights, critical evaluations,
and guidance to the field with regard to research directions and best
practices. First, we describe the various experimental probes and
complementary theoretical methods that have been used to discern the
mechanisms by which products are formed, and next we present our current
understanding of the complex reaction networks for CO<sub>2</sub>R
on Cu. We then analyze two key methods that have been used in attempts
to alter the activity and selectivity of Cu: nanostructuring and the
formation of bimetallic electrodes. Finally, we offer some perspectives
on the future outlook for electrochemical CO<sub>2</sub>R.
