The field of electrochemical carbon dioxide reduction has developed rapidly during recent years. At the same time, the role of the anodic half-reaction has received considerably less attention. In this Perspective, we scrutinize the reports on the best-performing CO 2 electrolyzer cells from the past 5 years, to shed light on the role of the anodic oxygen evolution catalyst. We analyze how different cell architectures provide different local chemical environments at the anode surface, which in turn determines the pool of applicable anode catalysts. We uncover the factors that led to either a strikingly high current density operation or an exceptionally long lifetime. On the basis of our analysis, we provide a set of criteria that have to be fulfilled by an anode catalyst to achieve high performance. Finally, we provide an outlook on using alternative anode reactions (alcohol oxidation is discussed as an example), resulting in high-value products and higher energy efficiency for the overall process.

“…CO 2 electrolyzer based on solid electrolyte was successfully extended to the derivation of pure acetic acid solutions via ECR, highlighting its great potential for practical application. [152,153] Methane: Eight electrons are required for CO 2 to CH 4 conversion, and a suitable CO binding affinity on the electrocatalyst is essential for deep reduction. Among established ECR catalyst systems, Cu-based materials were identified to be the only pure electrocatalyst system which could drive the deep reduction of CO 2 with appreciable activity and selectivity.…”

“…In this case, the main product is CO. Only the binding energy of CO and Cu is listed in the middle area. Therefore, Cu is the only metal catalyst that prefers C2+ [15][16][17]. Unlike producing CO, HCOOH is generated from HCOO*, which binds to the surface of the catalyst through 2 O atoms [18,19].…”

Producing chemical fuels from sunlight is a sustainable way to utilize solar energy and reduce carbon emissions. Within the current photovoltaic-electrolysis or photoelectrochemical-based solar fuel generation system, electrochemical CO2 reduction is the key step. Although there has been important progress in developing new materials and devices, scaling up electrochemical CO2 reduction is essential to promote the industrial application of this technology. In this work, we use Ag and In as the representative electrocatalyst for producing gas and liquid products in both small and big electrochemical cells. We find that gas production is blocked more easily than liquid products when scaling up the electrochemical cell. Simulation results show that the generated gas product, CO, forms bubbles on the surface of the electrocatalyst, thus blocking the transport of CO2, while there is no such trouble for producing the liquid product such as formate. This work provides methods for studying the mass transfer of CO, and it is also an important reference for scaling up solar fuel generation devices that are constructed based on electrochemical CO2 reduction.
