Details:CO2 contamination is well known to be one of the major causes behind climate change due to its major role in the increase of the so-called greenhouse effect. Ways to transform this gas into different products which are less contaminant and more useful to society are therefore being researched with both environmental and energetically purposes. Current technology focuses on the design of new catalysts and new materials to perform better reactions which involve less H2 coevolution. However, the results that are provided are always related to a specific time and conditions, which makes these non-reproducible if those exact circumstances are not met. We present in this research the evolution in time of the Faradaic efficiencies of the different products resulting from CO2 reduction in copper electrodes. H2 coevolution is indeed a factor that increases as the chemical reaction goes on in time. The origin of this coevolution is explained in this presentation, as well as the time evolution of the different C-based products which are obtained as result of the CO2 reduction. | ||
