With respect to their moderate CO adsorption energy and moderate hydrogen precipitation potential, copper (Cu)-based catalysts have been identified as the most viable catalysts for the electrochemical conversion of CO2 to ethylene (C2H4).
However, the CO2RR’s high overpotential into C2H4 and bad selectivity, low current density, and low current density severely restrict its industrial applications. The complicated reaction process is still unclear, which makes the creation of catalysts difficult.
The Global Copper-based Catalysts Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Approaching commercial CO2 electrolysis requires the development of novel copper-based catalysts, which is a significant move. When Nrskov, Koper, and their colleagues developed the computational hydrogen electrode (CHE) method and examined the C-C coupling pathways on various copper single crystals, interest in the field of copper-based CO2 electrolysis was rekindled.
The ability to customise copper-based catalysts by altering their morphology, tuning their valence, and creating alloys has made significant development recently. However, there are still unanswered issues regarding the physical makeup of the active sites in C-C coupling and product bifurcation.
Researchers can examine the trend in copper structure evolution under reaction conditions and map out structure-property relationships using in situ spectroscopy and microscopy techniques, which can be used to develop catalysts. However, it is challenging to depend solely on experiments for the design of catalysts due to the spatial resolution limitation and the challenge of quantifying atom-molecule interactions.
Therefore, a key instrument is the combination of theoretical calculations and in-situ characterization.
Furthermore, it is critical to constantly develop straightforward synthesis methods that are easily scalable in order to achieve precise control over the atomic arrangement of catalysts in order to obtain the desired results under the conditions of large-scale application.T
The system of CO2 reduction must satisfy a number of requirements in order to achieve the practical applications of copper-based CO2 electrolysis. The first requirement is a high current density, also known as a high reaction rate or activity.
Fast kinetic reaction rates enable product generation while maintaining a small environmental impact and maximising capital investment. High Faradaic effectiveness is the second. (i.e., selectivity). Enhancing the target product’s selectivity not only increases CO2 usage but also lowers the expense associated with downstream product separation.
