The development of new and efficient separation technologies to remove formic acid from the electrolyte can significantly improve the economics of CO 2 to formic acid.
Do electrolyzers affect the concentration of formic acid and formate in CO2 RR?
It has been well documented in the literature that the concentration of formic acid and formate in CO 2 RR is influenced by the choice of electrolyzers.
Does CO2 RR improve the performance of formic acid and formate-producing electrocatalysts?
In this review, some fundamentals of CO 2 RR to formic acid and formate (e.g., cell design and molecular mechanism) and the critical aspects that must be considered to improve the performance of formate-producing electrocatalysts (i.e., overpotential, selectivity, and stability) are first provided.
Can electrolyzers produce formic acid at high concentrations?
Designing the electrolyzer has been reported to be an effective strategy for producing formate, as well as other products, at high concentrations. For example, a three-compartment cell configuration by Yang et al. [40, 41] can produce formic acid at high purity and high concentration (up to 15–18 wt%).
Do electrode electrocatalysts produce high-concentration products (formic acid/formate) in CO2 RR?
Although few reports have been focused on the studies of high-concentration products (formic acid/formate) in electrode electrocatalysts of CO 2 RR, we will review especially electrode design strategies that produce high-concentration of formic acid/formate via increasing FE, current densities, and keeping stable long-term operation simultaneously.
