Abstract

With the global consensus that anthropogenic CO2 emissions are dangerous and should be mitigated, utilizing CO2 as feedstock for synthesis of chemicals and fuels represents an important strategy. A promising approach is to electrochemically reduce CO2 into value-added products such as carbon monoxide, formate/formic acid, alcohols, aldehydes and hydrocarbons, using renewable electricity to drive electrocatalysts that will mediate this reduction efficiently and selectively. The first electrochemical reduction of CO2 was introduced back in the 19th century (when only CO was detected as a product), but it became more popularized in the 1980s of the 20th century as a consequence of the great oil crisis and the awareness of global warming in the 1970s. The number of publications in this topic is rapidly increasing every year, but experimental methods and data representation frequently differ from publication to publication, potentially leading to confusion and misunderstanding. There are several important parameters and conditions that should be standard issue in every publication. These parameters include [1]: Onset potential for the corresponding electrocatalyst, Faradaic Efficiency for each product, partial current for each product, stability (durability) and turnover number of the used electrocatalyst, and furthermore the experimental conditions in terms of the: purity of the used chemicals, purity of the carbon dioxide, electrolyte preparation, etc.
